98 regal s.c. only idles when warm-please help-

[pete_704]

i have a 98 buick regal gs supercharged 60,000. The car stalled out one day so i jumpered the fuel pump resistor and it ran fine for a couple weeks then it did it again. I bought a fuel filter and a new fuel pump resistor, installed them both and everything went good for a couple days. when its warm the car idles at low rpms and it stalls out when you press the gas down. but I could drive 70mph for an hour but i slow down though a town and it wants to run rough until i let it cool or keep starting it. help

Unplug your air mass and see if it it runs better. If it does you ned a new air mass, if it doesnt then you may have a fuel issue. Check fuel pressure too.
