> A guy I work with has a 91 Pont grand am that has a slight problem I can't figure out. When he starts it when it is warm out and hits the gas it will stall. If he manages to get it going it surges about every second. He has tried a new prom and that didn't help (before he asked me about the problem). when it is surging down the road he will stop shut the car off and restart it and it usually fixes the problem. sometimes it don't so he shuts it off again and steps the gas to the floor and back and starts it again and it usually works. That kinda sounds kinda like a TPS but that should set a code and it don't have any set. I thought if it was computer related someone may have ran into this problem before.

First, check for a vacuum leak.
Second, check the regulated fuel pressure.
Always check the obvious before blaming sensors etc.
