SOURCE: 96 Ford truck engine lIght will not go away.

this is the problem with code readers they bwill tell you the code and sometimes even have a reset feature. However they do not tell you the parameters and don't have an drivability feature so you can not test the ecm and all the sensors or modules while engine is running. diagnostic scan tools are very expensive and hard to use unless you have been trained to do so and PEP BOYs is not what I call real reliable mechanics to begin with. Now I concure with toddG on his reasoning in what might be the potential fault. if your vehicle is running rich or lean your O2 sensor will pick this up on the exaust side, however it is not the sole sensor responsible for the ecm adjusting the fuel air mixture.. you stated that you have switched out several o2 sensors and the fuel pressure regulator, but there is also you mass air flow sensor, your TPS sensor, as well as your map sensor these are worth checking out and just because a faulty sensor is the problem doesn't mean you will get a code each time. the system is built with redundancy in order to keep the vehicle running. in order to get the best possible diagnois take it to a shop where they have a full diagnostic scanner this will have not only OBD1 and OBD2 but cam protocol as well. while the tech is scanning the vehicle he will be able to see how the engine is performing under realtime conditions. please rate this as well as change the rating for toddg because he did offer a valid suggestion

SOURCE: 2002 gmc yukon, rich fuel code, low fuel pressure @40

you may have two oxugen sensors on your yukon. if so the oxygen sensor that controls that bank may be bad. from what you mentioned in your complaint, it sounds like it is the oxygen sensor.

SOURCE: 2001 Tahoe: Hard to start, idles rough, check engine light on.

Flashing check engine light is missfire, fuel pump probably causing multiple tries to start.Having to build fuel preasure,vac leak on one side of intake probably causing rich/lean condition.Also check back preasure to cat ,Sound like you are moving down right track.Mas air flow would probably set lean code bank1 and lean code bank2

So I drive a 1999 chevy Cavalier and ive been having many problems with it. It blows black smoke sometimes from the exhust, on the hot and cold gauage the needle works its way to the hot end all the time,...


Hi,
It sounds like you have alot of problems which may only be a couple.
Have the coolant thermistor checked, it sounds like this is not switching off and causing the engine to over fuel, making it run rough and blow black smoke out the exhaust.
Have the engine thermostat checked it maybe faulty causing the engine to over heat., have these done and see how you cars goes then.

I just bought a 1986 BMW 325 that starts fine when cold. When the engine is hot and I try to start it puts out black smoke and idles rough and dies. Where do I start to look to fix this?


Coolant temperture sensor. Look at the front of the cylinder head. There will be a square 3 pin connector. This should be the one you need to replace. What happens is that it is stuck telling the computer that the coolant is cold thus providing more fuel to start. Once the system is warm this excess fuel is not needed and can create the black (raw fuel) smoke that is coming from the tail pipe once warm. This is a very simple repair. Let me know if you need anything else.

After starting car it sputters and white smoke from exhast. I drive the car for 5 min, sputtering the whole time, and turn it off - will not start until it is cranked and gas pressed for couple min. Then...


White smoke is usually from water and water will make the car splutter. Did you get water in your tank at some time. If you have water in your fuel, you will have to drain the tank and refill with good fuel. The engine will run fine once it is hot but if a lot of water goes into a hot cylinder it can cause a lot of damage.

If an engine turns over it is cranking, do you mean it cranks but won't start running?? Have you tested for spark and fuel pressure when you have a crank and no start? That is the 1st thing to do, until then you and I are guessing, and that gets very expensive very fast.
