Every body want’s a quickie. Plastic head lamp lens polishing.
This head lamp lens was very hazy. Both head lights looked the same way, hazy. The driver did not notice the lights being dim. Once I sold him on a quickie polish, he liked that the front of the truck looked new again. The next day he called me. He was in shock, he noticed right away, that the lights worked better.
Many of today’s head lamp lens’ are made of plastic. The plastic may become discolored and fade after many years of service. Hazy or yellowed head lamp lenses will reduce the light coming out of the head lamp fixture. The Hazy condition acts like a diffuser, making the light travel less distance down the road. A yellow lens condition will diffuse and change the color of the light. Both conditions will reduce the distance your head lamps can project down the road.
Hear at the shop, I have three levels of lens clean up.
2 Step Quick Polish: Clean the surface and polish the lens with a cleaning wax.
4 Step Polish: Clean the surface, polish with cutting paste and then fine polish plus apply a wax sealer.
8 Step Sand & Polish: Clean the surface, sand plastic in 3 steps, polish in 3 steps and then apply a wax sealer.
Most of the time a 2 step quick polish is all most cars need. The 4 step is for very heavy hazy and yellowing. The 8 step polish is for pitted and scratched lenses. Some times very deep damage will require lens replacement.

I just replaced my tires last month. Well, sort of.
The client in question, did replace the tires on this month, but it was 3 years ago this month. Time just zips by, and I have this happen to many clients, they lose track of when they last visited the shop. That is why we mail out reminders to clients, so they come in for service regularly.
I see 4 to 5 cars a week that need tires. So why do drivers wait till the tire fails? Why wait till you are on the side of the road.
I blame it on an old school idea, the myth is that Abraham Lincoln’s head is a good judge of tread depth. In the last couple years I have seen many automotive articles on tire wear and when it’s time to replace the worn out rubber.
Penny @ 2/32″ of an inch vs a Quarter @ 4/32″ of an inch.
When you use a penny to judge the tread depth, you are waiting too long to replace your tires. Waiting till your tires are at 2/32″ of an inch to replace them puts you at risk of hydroplaning in wet conditions.
Hydroplaning; “Verb” To slide uncontrollably on the wet surface of a road : a motorist whose car hydroplaned and crashed into a tree.
Many tires may still have tread in the center, but may be worn at the edge, or worse. Your tires could be age cracked, or have cuts on the side wall from hitting curbs. You must look at the condition of the entire tire, not just the thread thickness.
I know, I live in Arizona. It never rains in Arizona, right? Well the fact is, yes, it does rain in Arizona just not very often. But when it does rain, all the oil in the road rises to the top of the wet surface. That makes the road very slick. Any tire at 2/32″ of an inch will slip, slide and lose traction very easy in that type of wet condition.
So I like to use a Quarter, I keep one in my pocket to show clients how important thickness is when the road is wet. A Quarter will give you 4/32″ or 1/8 th of an inch of tread thickness. I use 4/32″ of an inch as a guideline for tire wear. Many tests have shown that tires worn to 4/32″ of an inch will still grip the wet road and bring your car to a safe stop.
The video below is showing a tire that is worn too much, it needs replacement now. If you look at the center of the tire you can see the tread is still thick enough that it could give the owner the idea the tire is still good. The client did not think the tread was that bad till I showed him up close how cracked and worn the tire was. In fact all 4 tires looked just like the one in the video clip. He only came in to get the fluids checked and the tires aired up because he was going on a trip in the morning.
So as your tire wears down below 4/32″ it will start to lose traction when the road is wet. Tests on tires looking at tire wear vs wet traction showed that at 3/32″ of an inch the wet stopping distances starts to increase by 15 to 50%.
At 2/32″ of an inch almost all the tires tested showed the cars using over double the amount of distance to stop. That is almost 100% more stopping distance needed when the road is wet. Replacing your tires at 4/32″ is a good idea. Think safety first.
By the way the client was very happy we found this before he had a break down. With 4 new tire an oil change and new wiper blades he was ready for his trip.

An engine miss fire feels like a bumping sensation. Most of the time, this is noticed by the driver when accelerating. A miss fire condition may cause the Check Engine Light to turn on or start flashing at you.
This is a spark plug with carbon tracking. The dark black lines running left to right in the center of the image is a carbon trail caused by a faulty spark plug wire. This type of condition will cause a single cylinder miss fire.
If an engine miss fire condition is causing poor tail pipe emissions, the check engine light will start to flash on and off.
When you see the check engine light flashing at you, do not continue to drive the car. Get it in for repairs right away. The catalytic converter maybe damaged if you continue to drive the car with the check engine light flashing.
A Catalytic Converter damaged by a miss fire condition. A miss fire condition will melt down a converter very quickly.
A catalytic converter is not chump change. On a Nissan Pathfinder, I just replaced both front catalytic converters on the Nissan and it was related to a miss fire condition. It was over $1,400.00 just for the dealer cats.
This set of worn spark plugs was causing a DTC P0300 on a Ford 4.2 V6. The plugs are 8 years old with 102,000 miles of use. The engine needed more parts than just spark plugs. This set of plugs also shows oil build up, the engine was due for a valve job on top of all the other needs.
If the check engine light is flashing, get it in for repairs!
OBD2 cars today can store a code that will direct the mechanic to look at a specific area.
A good example of this is when you have a DTC P0302 miss fire detected on cylinder #2, you have a place to look (cylinder #2 has a miss fire). You just have to look at things that would affect cylinder #2.
Oil fouled spark plug, this plug was causing a single cylinder miss fire. (DTC P0304)
On a DTC P0300, this is a random miss fire condition that could be caused by anything. Anything that changes the air/fuel mixture to all of the cylinders in the engine at the same time.
A dirty MAF sensor can cause this type of change to all the cylinders.
MAF: Mass Air Flow Sensor, is a sensor that takes reading of the incoming air into the engine and sends a signal to the computer. The signal is used to make fuel system, cam timing and ignition timing adjustments.
The driver may not feel the engine miss fire with a DTC P0300, but the driver should see the check engine light turn on. Other things the driver may notice. The engine may feel like it is not responding crisply or the driver may notice that the fuel economy has been poor.
A couple other things that can cause a DTC P0300. Poor engine compression or an engine that is out of time due to a faulty timing belt or timing chain. A large centrally located vacuüm leak or a restricted exhaust system.
——————————————————————————————–
DTC P0300 Defined: Random Cylinder Miss Fire, this condition could be caused by any parts attached to the engine or parts inside the engine. You have to look for any condition that will change the air/fuel mixture, spark or compression to all the cylinders at the same time.
DTC P0301 Defined: Miss Fire on cylinder #1 or any cylinder that the code lists. (P0301, P0302, P0303, P0304) The last number in the DTC is pointing to the cylinder that set the code.

I see many cars that need love, but I find it odd when you show someone how bad something is and they still feel it is not needed. That is just crazy.
It is the clients choice to do what they want, when they want, but waiting till it is broken just does not pay off in the long run. Preventing a break down saves time and money.
This filter was from a Toyota Sequoia. It was over due and blocking the air flow.

I have clients that keep the car they drive at (A+) ready for the road condition. Everything is in good shape and the car looks and operates just like new.
At the opposite end of the scale is the fix it when it breaks clients. Most of the time this kind of car is not ugly on the outside, but it is in need of love under the hood.
Every car will need repairs someday.
Waiting till it breaks and you are at the side of the road is no fun. Only fixing things when they break will cost more in the long run. It may not feel like it at first, but if you put the numbers on paper they add up to more over time.
Starting a repair savings fund at your bank is one way to plan for future repair needs. I have three clients, that use a change jug. All spare change goes in and stays in till it’s time to service the car. Basic maintenance costs less than you think.
Getting your car repaired is as fun as going to the doctor, but If you plan for the repairs needed, it will take the sting out of the visit.

When your mom said, comb your hair and brush your teeth, did you do it?
Most kids do not listen to mom or dad. They respond as if they are listening, but it went in one ear and out the other.
Selective listening is what this is called.
As you get older you may grow out of it. I have car owners that selective listen all the time. They only hear what they want and the rest falls to the floor.
Part 1: Recently a young woman (mid 20’s) was in denile about the cars needs. It was explained three times, in different ways. She just did not understand why the car needed repair. The client only wanted to hear what she wanted to hear, she did not listen.
Part 2: Three days later the car came in on the hook, broken. The client was mad.
Why did my car break down?
When we explained what happened, she said, how can that be, you just checked it out and said nothing was wrong. After reprinting the last invoice and showing her the area outlining the needed cooling system repair, it finally hit her. The car needed repairs on the last visit and she did not listen.
Listening is an art. To get good at listening, you have to practice doing it.

Really, you do not have enough money to maintain your car? I run into this statement often. This time it was a single mom with two little ones. She said, she barely had enough money for the oil change, much less any repairs.
The repair needed was a cooling system hose @ $63.00 parts and labor. I could not let a good car over heat and turn into a bigger issue. If the engine overheated, I knew she would have no money to fix that. So I gifted the repair to the client.
Then I issued a challenge to the client. I handed her a two-quart empty juice jug, it was clean…
I asked her to take any spare change she gets and drop it into the jug. I also told her not to cheat the jug. Leave the change in the jug till the next oil change. Then bring the jug to us and our morning guy would run the jug over to the Coin Star Machine during her next visit for repairs.
Well, the client came in and she was shocked when the jug was counted. She had enough money for the oil change and two other maintenance needs.
Spare change can go along way if you do not cheat the jug.
It does not take much money to maintain a car. maintenance is on going and if you ignore it, the car will break down. The national average for a basic economy car care is $.08 per mile driven. This is does not include European cars, big trucks, suv’s, 4×4’s and sports cars.
I have many cars come in every year with rat or field mice damage. The little critters chew up wires and hoses, damaging your car or worse causing a health hazard by getting into the A/C system. If you have a car that sits for the season, the little critters can cause hundreds of dollars of damage in just a couple of weeks.
On many cars, critters can get up into the small spaces and start building nests. The video above is showcasing what I did to stop field mouse from nesting in a Lexus A/C system air intake passage. The client had replaced the cabin air filter 6 times in 4 months. I had to make a repair inside the A/C case related to the damage so this is what I did to keep the critter out of the inlet passage.
Rats and field mice can damage a wire harness in hours. One way to combat them is to use an ultra sonic pest repel unit, if your car is parked for storage this works the best. Local hardware stores have them and you can find them on Amazon. You have to plug them into a 110 volt power outlet, but if you can use this product, it is effective.
Wire and hose repairs we do at the shop, are wrapped up with rat tape. Rat tape has a spicy kick to it. It has a hot pepper additive in the tape that makes the rat think twice about chewing on it. Rat tape works about 90% of the time.

Summer time is here. Summer heat will place extra load on your engine. During the hot summer months it is advised to use top-tier gasoline. (91 octane) The engine systems in modern cars today do a great job to control timing, but sometimes it will still ping. Top tier gasoline most of the time will quiet the ping or rattle sound.
The engine knock sensor pictured above was causing a nasty ping on a Nissan Pathfinder. The sensor is located under the intake manifold, not easy to change. The one on the left is the new knock sensor. The sensor on the right was still working, but not correctly due to the broken outer plastic shell.
If you hear the ping sound, do not ignore it. Something could be wrong. An engine will also ping if it is over heating. If your car is 3 years old or older, inspecting your cooling system regularly is very important. Stop in at the shop if you have a ping or rattle condition. A prolonged ping condition can damage internal engine parts.

When a DTC is stored in the PCM, (Power-train Control Module) you would figure that the stored code would point directly to the fault or the engine would run poorly.
Some codes will be very specific to a sensor or fault condition.
DTC P0102 is a simple code with a very specific fault condition. The MAF signal is low during engine operation. The normal idle frequency of a good GM MAF is around 2100 to 2500 hertz.
The code will most commonly set anytime the hertz signal drops below 1200 hertz during engine operation.
This condition is easy to check with a lab scope or a OE level scan tool. I do not recommend to DIY this type of intermittent fault unless you have the correct tools. It is easy to cause more harm than good or replace parts that are still good.
If the condition is intermittent it could take time to duplicate the fault. Many parts houses will sell you a MAF sensor as the most common part replaced. When the condition is intermittent you have to duplicate the condition to I.D. the real cause. The MAF sensors can go bad, but MAF sensors are not the most common failure part.
Do not buy a re-manufactured MAF, ever!
A man-made or age related failure is more common with an intermittent fault. I see many damaged electrical connectors, faulty Idle Air Control Valve, poor handling of the wire harness during service work, damage to the MAF sensor, poor quality accident repairs, faulty chassis grounds or age related circuit failures may cause an intermittent conditions.
This dirty throttle chamber was causing the clients issue. The build up was cutting off the air and causing the engine to dip so low in RPM that it would go into a stall when coming to a hard stop.
One week earlyer I had a Buick Park Ave that had the same code, but it had a bad MAF sensor. Testing is the best way to know what is faulty. If you have a check engine light on. Stop in to the shop and let us take a look.
