Well theres a local Labor Day car show this Sunday that I'm hoping to get my car in... I took a second last year so this year I'm going for first!! Anyways, my cars throwing a MAP code (p0168) I think a P0300 and a 02 code. Know its still running rich so I'm thinking the new tune and the new 02's and plugs will get rid of the two but whats up with a MAP code? Would it running rich cause this? Theres 55xxx miles on that sensor. I did steam clean my motor but it ran fine the next day, after work it started backfiring bad. I just need some help. Anyone know of an easy way to get the plug wires on tight? (msd wires) I'm getting fustrated with this. FYI it had a MAP code on it before I cleaned the motor. just started the mis fire and 02 code after it had gotten wet. Thanks to all...
