These are all the mods are the car, I do have a tweecer too that I havnt used just yet.....
I can smell fuel in the exhaust and it falls on its face at 2500rpm I have tried everything need some help! Timing has been checked it sitting at 14.5 or so! help please
Need more info on the computer and the Mass air. The computer is for sure a cobra unit? What is the Mass Air, is it a Cobra unit as well? Just asking since the cobra computer compensates for the injectors in the computer and not the Mass air.
the 02 sensors are furuther down and they don't heat up. It's telling the computer it's lean and it's adding more fuel that I don't need My 02's are brand new and no vacuum leaks. Keep giving me code 91. I know for a fact the car is not lean whatsoever....in fact it's so rich it's to the point the exhaust burns my eyes. I have a tuner and pull %12 fuel out a idle just to compensate but its' more of a band aid than anything else at this point. I've yet to have someone tell me how to solve the issue...
