Plenum porting question?
I have a question regarding the fact that I ported a plenum and replace my stock plenum with it. My iroc ran fantastic with no problems before hand. Now with the ported plenum it will not idle and the maf throws a 33 code. I will disconnect the maf and it will idle and run off the tps and o2 sensor. Has this happened to anyone else before
