Question about 2002 Chevrolet Silverado 2500HD

1 Answer

Check engine light

My check engine light comes on and off intermittently. I've checked all fluids and batteries. Everything is fine, even after driving for 10 or so miles. Is this possibly involving the emissions? If so, is there an easy fix?

If the light was flashing when it came on, then it means your engine is misfiring.

A solid light can mean anything from a loose/faulty gas cap to a transmission issue.

This light comes on when the computer detects a fault of some sort in its diagnostic tests. If it keeps detecting this issue, the light will remain on. If the light turns off, then it has detected that the issue may no longer be present.

In order to find out what the exact reason was for your light, You need to have your car computer scanned to retrieve the code that the computer would have stored when the light triggered. Most garages will do this free of charge. The code will tell you what may have caused the light to initially turn on.

2002 Subaru Forester misses/runs poorly with slow acceleration when hot with a/c on especially after running 50-60mph on interstate. Problem is intermittant. Runs fine with excellent acceleration...


I have the same problem. But my check engine light comes on when this occurs. The car runs fine otherwise. The problem manifests when it's hot out and I've been driving for a while with the A/C on. When I stop somewhere (like the supermarket), shop, and get back in my car. It starts fine but when I put it in gear to go, it's extremely sluggish for a few seconds and the check engine light comes on. Then is runs fine but the check engine light remains on. The next day when I start it, the check engine light is not on. Also, I recently had the head gasket replaced. I took it back into the shop the first time the check engine light came on. The mechanic checked it and said everything checks fine. He re-set the light saying to keep an eye on it and bring it back in if the check engine light comes back on. It ran fine for 1.5 weeks and now this problem has started to occur.

Did you find anything out dwbradway? I wish I had a solution for you but I just have the same kind of problem. Any help would be appreciated!

Engine repair lights


check engine lights are a constant hassle in any vehicle you buy. If you have checked the motor out and all the fluids are topped off, take it over to an Auto Zone and or Checker, and have them test other things such as your starter, alternator, battery. If these are all in good shape and no one can give you any idea, then it's most likely just in the wiring... sometimes the check engine light will throw even when nothing is wrong... if your car is running smoothly... no worries.
