well before i do that i was wondering if it might be the air control valve like you said before..i was reading a little bit and they said that a defective acv could be the reason for afterburning in the exhaust..and well my car does that realy bad..like everytime i get to about 5 grand and then shift it pops really loud..so if the acv was defective that would make it not idel good right?
