My car was parked and I push down on the gas pedal it spit and sputter and I felt hesitation in pedal and when im driving it jerks. So far I replace fuel pump, coilpacks, throttle sensor and body and done a tuneup.

Scan for codes first then check resistance of crank and cam sensors.

Take a paper clip and cross A&B on the aldl with key on and count flashes of check engine light. It will flash three time for one number and three for next like 1 then 2=12 then go to popular site links on lh side of site and look under obd 1 gm for your codes. The aldl is on the bottom lh of dash under steering column you'll see it. If not got to same area and it will or should show where it is. If not have a pro do it or someone familiar with cars.
