Hello,
This sounds wierd, car will idle good when cold. When it warms up it gets stupid and surges, idles high sometimes and will die sometimes as well. i just put a B303 cam in car and it dont even sound like theres a cam in it except for when its cold. After it gets warm it has no lope to it hardly at all.
The car has a stock bottom end, new GT40P heads with Comp Cams valve springs to match the cam. All new FMS valvetrain parts besides the springs. Edelbrock Performer intake with matching 70 MM TB, TPS is set at .95 with key on and motor not running. A Pro-M MAF calibrated for the 19# injectors which are the stock ones. Aeromotive fuel pressure regualtor with pressure set at 41 at idle with hose on. Car smells like its running real rich at idle as well. I have off road H pipe could the 02 Sensors cause this much trouble? The car also has a FMS idle adjuster plate on it which did not help at all. Can anybody please help me out? Thanks!!!!!
