I have a 92 GT mustang with alum heads..big cam..roller rockers..and 24lb inj with a new mass air calibrated for such....sometime I get a rolling idle like a vacuum leak...sometimes I don't...I also get a bad studder when I ease into it..instead of punching it...then it pulls like a frieght train.
Has new plugs, wires, and a msd 6al.
should I just knock the varibles of things to act up down and go carberated?
Oh yeah my ex poured antifreeze, oil, and who knows what else in my tank which I replaced.
Any advice?
