95 century with 3.1 engine quits running

Ok I have a problem. It runs fine when it is cold but when it warms up it dies. It has spark and fuel pressure is correct. I replaced the coil packs and the module already. It starts popping through the throttle body and then dies. as soon as it is cooled down it will start and run fine again until it is warm and do it again. Any help would be appriciated.

The quickest thing that comes to mine when dealing with my century is the I.A.C. unit or intake air control. if your idleing rpm fluctuates when heated up and eventually just dies till it gets cooled down, its a probable cause. they can be cleaned but your most likely gonna wanna just replace it for 46 bucks in no time by yourself. As long as you don't handle it roughly they callibrate themselves so no worries. worth a shot.

I wouldn't rule out a bad EGR valve, because it might open when hot!
