    I recently acquired a 90 gt. the car needs help. I'm sure she has edelbrock upper and lower intakes, and heads. I'm told its an F303 cam. i can see msd ign, and coil, black (24lbs?) injectors. its got the surging idle nightmare. I've been throughout the check list about 3 times. No vacuum leaks that I've found, I replaced iac, pcv O2s tps. i got the tps set at .97. all with no result.... Any thoughts?
