Hey everyone i got an 06 ss/sc and i put on the fujita intake, zzp header and downpipe along with the gmpp exhaust. well my issue is constant misfire in all 4 cylinders on an idle scan from hptuners. i changed out the plugs and i am still getting really bad misfire. my car was built on 05/06 so i have to get the time chain fixed do you think that will help?

 

anybody?

 

Im having the same kinda problem. I was told aftermarket intakes are notorious for improper MAF sensor placement and result in skewed air/fuel ratios and can cause lean conditions not necessarally missfire. is ur check engine light on? i just found out of that problem and im going to put my stock air box on and see if that helps.

 

I have an AEM intake in mine. I didn't notice any missfire until I put on My 3" catback two months later. But yeah I feel yeah

 

well the problem was solved by the dealer i had a bad injector. it was stuck closed for some reason. i rescanned and got no misfire
