ok guys i finished my PI intake swap this morning and everything went together smoothly. Here is the problem I have a severly miss fire after the swap and when I start it up my car stays at over 2000rpms for 10-20 seconds.It also hangs in the rpms longer than it used to like when i rev it to say 2500rpms it takes forever for it to idle back down. THe miss fire seems to be getting better the longer i have the battery connected and more run time it has on it. Guys what could it be? I have a check engine light on also but i think that is because i dont have the second temp sensor pluged in because I have to tap it into the side of the block. As my Pi intake doesnt have the aluminum crossover for me to tap it into. Could this sensor be causing my problems?
