2004 Chevy Trailblazer 6 cyl Four Wheel Drive Automatic 88,000 miles
hi, I am a one-owner of a 2004 trailblazer 6 cylinder. I have been having a problem with missing and rough idle. The problem has been gradual and getting worse. The service engine light stays on and intermittingly flashes when the miss is really bad. I have had a tune up. Coils, plugs, converter change, fuel pump and filter, secondary air pump, and camshaft sensor all changed. The secondary air pump was filled with water when he changed it. During a diagnostic run I had over 500 misfires in cylinder 3 and over 60 in cylinder 4. I am at my wits end. No one has been able to know what my problem is and how to fix it. I have spent literally thousands and feel like it is driving worse everyday. Could this be egr or any ideas?
