non 3rd gen, but still Pontiac, please help!!
Ok, 89 Pontiac Grand Prix, runs great when it's cold, as soon as you drive it for like 15-20 mins and it warms up it starts falling flat on it's face if you push the pedal anymore than like 1/2 an inch down. If you let off it will run smooth but you can't get over like 20 miles an hour. If anyone has any ideas I would really appreciate it.
