K so i have a 2006 supercharged gm stage 2 a month ago put a 2.5" catted downpipe, injen cold air intake, no problems , this past weekend put a cobalt addiction header on it. Got a cel all o2 codes 1 maf code, so i put a spark plug fouler in the downpipe after the cat, disconnected the battery for about 10 min, go to start it, ran for a little bit but very rough and just stalls each time i try. I cleaned the throttle body and the maf sensor still the same thing any help would be much appreciated thanks.

 

Oh man i was just going to post almost the same thing. I cleaned my MAF and my TB today due to rough idel. I ordered a new MAF so i will see if that fixes the problem...

 

Probably there poopy header causing the issue, that company sucks

 

I just put my CA header on the other day, I havent noticed any problems yet...
