Hi, I am new to this site, so I apologize in advance if I am posting incorrectly.
My car is a 1995 Mustang GT 5 speed with 92k miles. Mods to car, Kenne Bell supercharger setup for 8 psi, matching mass air meter and 42lbs injectors, 255 in tank pump. Custom dyno tune with smog pump and charcoal canister delete. Cold air intake, throttle body, MSD distributor.
Problem: car's idle will intermittently surge when started (rpm from 300-1000) and you have to essentially keep revving the engine to get it to correct itself, which it does. This only occurs when first starting, and seems to do it only when the engine is at operating temperature. I have read my codes and have nothing. The IAC has been replaced but made no difference. My mass air is a Pro M and I am thinking about sending it in for evaluation but thought I might post first and see if others might have suggestions. Thanks in advance!
