hey guys.. Took my car into the local shop because of a CEL. They pulled the code and all 4 cylinders misfiring. they reset it and told me to come back again when it turns on. CEL came back and it pulled the same code. all 4 cylinders misfiring. They checked the coil packs, spark plugs, ignition, and did a compression test. Everything came out ok. Anyone have this problem before? Any Ideas?

 

There is a really useful thread about what you should check, and there are a few things you haven't done.

I had a similar problem, originally misdiagnosed by the dealer. Turns out the injectors were somewhat clogged and replacement of all four eliminated the problem. It's been 10,000 miles and the CEL light has not returned.

 

What was the CEL code... I mean that would help a lot...
