I have a 02 35th anniversary 3.8 v6 camaro that recently the check engine light has come on. The engine seems to sputter while driving at low RPMS, and feels like there is loss of power. I have got several different trouble codes all the way from EGR valve to Lean mixture in Bank 1. I replaced the O2 sensor behind the cat already, new fuel filter, new plugs and MSD wires. Any advice on what it could be would be appreciated.

 

If the EGR valve is not seal off it will cause those issues at low RPMs. Along with about 20 other things that can cause the issue also.

I would clean and test the EGR valve first thing. Check out You tube for Cleaning and testing the EGR valve.

 

Without the actual list of codes it is hard for us to help you. If you can list the exact codes that are in the computer we may be able to help with your issue with more than just a guess.

I will have to get the list of them again. I know there were about 6 in all, the first one being P0420 and P0171. Also wanted to add that it has stalled a few times while driving when pressing the brake, during this time the oil pressure department but never below 40,then goes back up to 60 when accelerating, which I think is normal.

 

40 ish at idle and 60 while driving is the norm for the 3.8L engine.
