Misfires, Need help
#11
Hey guys just an update, taking it to a guy that specializes in domestic cars and has all of the GM specific computers, scope, tech II, ECT. As far as my other mechanic he said it would need a valve job, so im going to get a second opinion. Coils have been checked out and according to him there fine (replaced and tested). So im keeping my fingers crossed.

Here is a very informative article on misfires. Engine Misfire Diagnosis
If the misfire is random (jumps cylinder to cylinder) it could be an EGR problem or a vacuum leak.
