hey guys so my buddy throw together a mustang has quite a bit of money in it and the thing idle is outrageous it surges like crazy it will go from 900 to 1000 to 1100rpms. And i need some help diagnosing it. Im pretty sure its the injectors cause he has 30 lb injectors. And all it is is a 302 forged internals(D.S.S. motor) anderson cam get back on the size dont know it off the top of my head. gt-40p heads mill'd a tiny bit. fuel pres reg bbk cold air fender well, trickflow upper intake. and i think a c&j maf sensor. any one go through the same thing? or know what else might be causing this?
