Chevy Truck Repairs, My engine runs rough.

1997 Chevrolet truck with a 4.3 engine runs rough.

The owner has maintained the truck very well, but with 300,000+ miles on the clock you would think it would be all worn out, but it’s not. This is why maintenance is critical to the long life of your car or truck. This truck looks and drives great because the owner loves his ride. The rough running condition was not setting any codes.

(This was a No Code, Driveablity Condition) 

It was not related to the ignition system or engine compression. It was caused by a faulty fuel pressure regulator on the fuel injection unit. The only way to spot an issue like this is to know fuel delivery basics.

The failure was not computer related.

Some engine parts go bad slowly over time. The client did not know that anything was wrong. The client only said it felt rough at an idle and to check it out. This little monster below is the fuel injection unit from under the intake manifold. It is hidden from sight. So when it has a leak, you do not smell it or see it, but your fuel economy will drop when it is going bad.

The client may have noticed that the engine was using more fuel, but he does not check the fuel mileage regularly. The easy way to check fuel usage is to zero out your trip meter when you fill up the gas tank. Then at the next fill up, divide the miles traveled by the fuel used to re-fill the tank. Presto, you just found out what your fuel MPG is. Now, do this at every fill up and if you notice your mileage drop over 20% suddenly, you may need repairs or lighter feet.

Full Service Gas Stations 85016

A long, long time ago… Full service gas stations?

I remember the days when you could find a full service gas station in every local neighborhood. I worked the full service island at a Chevron station near my home town high school. Just about every kid in the auto shop worked at one of the local service stations. It was crazy fun and 5 gallons of free gas every week.

The owner had a great hook, fill up before 9:00 am weekdays and you would get a 16oz hot coffee and a car wash for free. The coffee was average and the car wash was just a basic wash, but people lined up for it. It was a hook.

Today it is hard pressed to find a full service gas station any place in the country. Full service gas stations are gone, a thing of the past. Anyway who would pay extra money for a gallon of gas just to have someone pump it for you?

The gas station I worked at had dozens of regular clients stop in every day for full service fill ups. Young or old, people just did not want to get dirty. Clients liked the personal attention. Everyone liked that we checked the car at every fill up. Checking the fluids, belts and hoses, airing up the tires and washing the windows. We took care of the clients ride.

Cars today still need attention. Waiting till it goes in for service every 4 to 6 months is way too long. Many things can happen in just 30 days. If you have a 6-year-old car or older you should be checking it regularly. Once a month you need to check the under hood fluids, air up the tires, toss out the trash and maybe give it a wash.

If you are in the neighborhood, stop in and let me take a look under the hood. I charge nothing to take a look. If I find something needing attention. I can give you an estimate for the repairs. The important part is to take a look. If your ride needs repairs, it’s better to fix it before you break down on the side of the road.

Are you ready for the “Summer Heat”?

It’s March & almost summer time. It’s time to get ready for the heat!

Everything inside, outside and under the hood of your car will see extra stress because of the extreme heat in Arizona. If you haven’t noticed it yet, Phoenix is a desert climate, dusty and hot. Every summer I see many cars that are not ready to take on the Arizona heat.

If you live outside Arizona and plan on traveling through Phoenix mid summer, this applies to you too.

The cooling system is a great place to start. Inspecting everything on the engines cooling system is very important. Leaky hoses, water pumps and radiators will let the coolant level drop slowly in the cooling system. Low coolant levels can quickly turn into an over heating condition ruining your engine. Reduced air flow due to bugs, trash or faulty cooling fans can lead to over heating just as easy as low coolant levels. Engine failure can be prevented with a visit to the shop for a full inspection of the cooling system.

You need air-conditioning to keep you cool in your car. let’s check it! Is the output temperature correct, do all the controls work correctly, is your cabin air filter ready to get the job done? Do you have any leaky hoses? Let’s take a look.

Have you thought about reducing the heat to the inside of your car? If you have regular clear glass. Window tint will help cut the heat load to everything inside the car. A high quality tint will reduce the heat inside the car by rejecting the sun’s UV rays.

A summer time inspection can be included with a regular oil change service. Waiting till you are at the side of the road is too late to act. Stop in today.

A/C Filter Maintenance

A/C air filters get dirty quickly in Phoenix, AZ

The normal interval for a/c air filter replacement is once a year or every 15,000 miles. In Phoenix, AZ it is very dusty, so filter changes may be needed more often. Today I found a set of original equipment a/c filters in a 1994 Lexus LS400. The car only has 96,000 miles on it and the owner only drives twice a week at best, the owner is a snow bird and this is the winter car that just sits at the house during the summer.

The car has been serviced several times with us, but the owner visits other locations. The client did not have an issue with the a/c, but it’s March and warm out so I turned it on Max just to check it. I noticed the air flow was weak when the fan was set on MAX air. So I took a peek at the a/c air filters.

I was stunned to find OE original filters in place. Some-how it was not noticed on the other visits to the shop. Overall changing the cabin air filter regularly keeps incoming air cleaner and duct air flow at peak output. If you do not remember ever-changing the a/c filters in your car, stop in at the shop and we can take care of it for you.

Check Your Oil!

When was the last time you opened the hood & checked your oil level?

Why wait, check it today!

A low engine oil level will cause internal engine parts to wear. Waiting till you go in for service may be too late to prevent wear from taking place. You can’t see the wear that takes place inside the engine, but it may be the difference between replacing the engine at 60,000 miles vs 200,000 miles.

I have seen car owners bad mouth a brand or product line just because of a failure related to poor maintenance.

This car is a pile of @!^&*!!

The truth is the car owner didn’t do his maintenance. Ignorance is bliss. Good car ownership starts with maintaining the things that wear on the car.

Tires, brakes, ignition & fuel systems, fluids, filters, belts, hoses, lights and wiper blades will wear out some day. Why wait till you are broken down at the side of the road to take action?

maintenance is ongoing and the key to the long life of your car.

I know in our rush, rush world. You may never stop long enough to remember about checking your own oil level, unless the engine makes ugly noises or the genie lamp turns on. Why wait, checking your oil level may save you from an engine failure.

If you are in the area, stop in at the shop and I can check the oil level for you. If your oil level is low often. You may have an oil leak. even a small oil leak can cause the oil level to be low in less than 30 days. Always fix oil leaks as soon as possible to prevent engine wear due to oil loss.

What is a genie lamp? Engine Repair Phoenix 85016

What is a Genie lamp?

This was one of the funnest & sad things I have ever encountered, but it was mostly a sad day for the owner of the car. The owner of the car in question did not know what the lights on the instrument panel indicated. The owner drove the car till it stopped. Once the car arrived at the shop, I asked the standard questions. The owner said they had a genie lamp on, but the car drove fine till the engine stalled. so I asked them to show me what lamp on the panel was turning on.

Keep in mind, I was puzzled about what the client was seeing. Because I have never seen a genie lamp on any instrument panel. 

The client turned on the key and pointed to the light that was on. It was the OIL LIGHT, but to them it looked like a genie lamp. Keeping a straight face, I said, a genie lamp would have smoke going up out of the spout. The lamp on the panel had a drop going down. The client just giggled. Then shock set in.

The client had no idea that the engine had no oil in it. It was just serviced at the clients local quick lube. The drain plug was tight, the filter was new and tight, just no oil. I was very impressed, the car went 14 miles before engine failure. The client said the light was on when they picked up the car, but they did not think anything of it because, it was on intermittently a week before the service. I did not say a thing. I Just gave them a price and the car ended up going away.

As a car owner, you should know some basics. You need to know how to air up your tires, plus check the oil and coolant. You should know what all the warning lights on the instrument panel indicate. You should know how to change a flat tire.

If you have questions about your car, stop in at the station and we will answer any of your questions at no charge. Knowledge is key to keeping your car in good shape.

DTC P0440 Evaporative System Leak Detected

The gas cap pictured above looks bad, the gasket is cracked and you would think it would be leaking, the odd thing is it seals up just fine.

DTC P0440 evaporative system leak detected.  This is one of the OBD 2 codes that every car owner will hear about at least once.  The code is for leakage in the evaporative system.  It does not indicate the gas cap is bad, but a loose or defective gas cap can trigger the code.  A faulty roll over valve on the top of the fuel tank can set the same code.  The code will set in the computer for any number of reasons, that is why we run tests to rule out the unknown.  The first test is the gas cap.  It is a part that can wear out from use, so it is a good place to start.

P0128 Engine Code Dodge Magnum

Dodge Magnum Check Engine Light on, code P0128

When the check engine light turns on, it indicates that the computer sees a fault.  When the engine computer sees the fault, it will store a code.  The code will direct the repair technician to an area to test.  Today I have a 2005 Dodge Magnum with a P0128 code.  This code is basically the same for any make or model.  This is a standardized code for O.B.D. 2 cars and trucks.  P0128 is for Engine Cooling System Thermostat Rationality.  The engine computer (PCM or ECM) predicts what the engine coolant temperature should be, based on the engine coolant temperature at start-up.  The predicted engine coolant temperature is then compared to the Engine Coolant Temperature Sensor (ECT)  The error between the two is calculated and integrated with respect to time.  When the Thermostat diagnostic runs, the integrated error is compared to a calibrated threshold and a pass or fail is then determined.  Many things can cause the code to set, but they all have one thing in common, Engine Temperature.  Any electric or mechanical component that can affect engine temperature readings will cause the code to set in the computer, even a faulty computer.

The image above is from the Dodge Magnum.  The black rubber body around the center disc failed.  (new on left vs old on right)  The rubber is in place to make a tight seal around the outer body.  This rubber sealing ring keeps coolant from flowing untill the engine reaches the correct temperature.  If coolant flows too early, the code will set.

The engine computer is looking at the coolant temperature to adjust timing and fuel delivery for best economy.  A faulty Thermostat can cause reduced fuel economy, poor heater operation and hard shifting from cars with automatic transmissions.

Cabin air filters

The air filter above is only 7 months old.

Heating and air conditioning systems on many of todays cars and some trucks have an air filter on the inlet side of the blower motor housing.  The filter helps to remove the small debris and dust from getting into the passenger area.  Service is normally due about once a year or 15,000 miles.  The filter will need more frequent service in a dusty climate.  In many cases the filter does not take long to change.  Air flow will be reduced as the filter becomes dirty.  Changing a cabin air filter video by HeyAnthonyAZ.

It was not like that before!

Ok, I understand.  So let’s solve this now.

As a service consultant I have some trouble with this statement.  For me, it indicates that the car owner came in with a condition that may of not been disclosed when the car was dropped off for service.  Lucky me, I document all findings from large to small.  If I am at fault, I will not side step the issue.  I will fix it.  It is not uncommon to have something happen during a visit, but if anything was to happen during a visit, we will not hide it from you.

Anything we find during the cars visit is documented on the work order.
