When I start my car stone cold it seems to idle just fine but when it gets up to temp the car won't idle. It will slowly get worse and worse then eventually die. I just replaced the mafs since the car wouldn't rev before with the bad one but now it revs fine and has good power. The car will not stall if I'm driving it normally but if I could to a stop it will stall. Any ideas? IAC? Theres no CEL present
95GT won't hold idle when warm

Dan, that TPS reading should have evoked the CEL.
It's not unreasonable given what the car is doing. Confirm that the reading is correct, and check the wiring going to the TPS (ohm out the TPS ground, check VREF, and check the sweep trend in the signal wire).
Take a look at your idle bleed screw - ensure it isnt run out too far. More than about 1.5 turns from seated yields some crappy idle characteristics for most folks.
I have some 94-95 idle setting tips that are a little off-beat once you get that far, if conventional methods are not cutting it.
Good luck.

See "Surging Idle Checklist for help with all your idle problems. The first two posts contain all the updates to the fixes. I continue to update it as more people post fixes or ask questions.
