P0507-DTC trouble
P2178-rich at idle
They replaced the ECM&BCM. It ran great until 3 weeks later, same problem reoccured, this time with a ton of exhaust backfires. Took it back, they said the exhaust was broken. Had exhaust replaced and now the problem has come back. I put brand new plugs in a week ago, ran excellent until a few days later. Now I only boost to 3PSI... I tried pulling the MAF sensor and plugging it back in to no avail... I had a look at the plugs and they are covered in black soot(running rich?)
Any suggestions? I had 2 boost tests done, no leaks. No vacuum leaks. I wonder if they didnt reflash the ecm for the stage 1? would that cause problems?
I have posted on the CobaltSS forum aswell, just hoping somebody with a mechanic background might be able to steer me in the right direction as I am loosing faith in my dealership
