Hey everyone. I have a '92 Gt vert and I have a couple questions about some add-ons.My car has an E303 cam with professional products upper and lower intake. I just put a pro m mass air sensor on with a K&N FIPK air filter, and a new accel coil. First off... the RPM seem way off. I believe the gauge was some what accurate before installing the coil, but now it doesn't go past 3,000. The other thing is the car isn't idling that great. Idles right around 6-800 rpm(if the gauge is right) It was running fine before I installed this stuff. I am wondering if the car needs to be tuned again, or should I just rotate the mass air sensor? The mas is calibrated for my car. I don't understand the gauge being off all of the sudden. I appreciate anyones feedback. I will upload pics of the car

good looking ride man! ive never really heard anything like that before. could be so many things. id say just take it to a good tuner or the ford shop and tell them.

wow i love your car. Now is the gauge off or is the motor only pulling to 3k? how does it run, does it feel like it lost power? does it search for an idle? did you set the tps?

Thanks for all the responses. I lost the post for some reason and just found it! The motor pulls all the way through the rev range w/ a little hesitation. I haven't checked the tps position yet. The iac is new and so is the throttle body. I just had my uncle re-time it for the idle issues. It still doesn't idle properly especially when cold. I plan on bringing it to a mustang tuner as soon as weather permits.

Well I played with the base idle a little bit and hooked my Pro-M mass sensor back up. I think I set the idle a little too high as the car doesn't settle. Still am having a little driveability issue just cruising in second. Car seems to have a problem when coasting to light applications of the throttle. Could this be the cam? I wish the weather would break here so I could drive it a little more.
