94 Buick LeSabre stalls when warm
 

Have a 94 Buick, replaced damn near everything on it in the past two years, 136,000 miles, starts up and runs fine when cold, but doing short errands, if I turn it off and try to restart when warm, it stalls out, but then will start up if foot is on the pedal. I've replaced the fuel pressure regulator, injectors, fuel pump, along with other electrical parts, and the gas cap. I get no codes and their are no gauges, just idiot lights. Any help would be greatly appreciated.

A questionable throttle position sensor would be my first check.


I would not go replacing that part unless it is tested and verified defective.

It might be cheaper in the long run to have a shop check it with the right equip before replacing a lot of good parts.
