hesitation

i have a 97 sl2. my saturn has 244.650 miles and always ran great. my problem started with a miss fire #1. wires were bad . new plugs and wires. . i also replaced the coil packs. then i replaced the engine coolant temp sensor (brass). new fuel filter also. i have no codes and no check engine light. the car is fine at idle. the car runs and drives great in the cold mode condition. as soon as the car gets operating temp, it acts up. it has an off idle stumble when your driving. i can acceralrate wide open throttle and it will go. no problem. it is only when first hit the pedal. the tps throws no code and i did a resister check and it was smooth up to 100%(wot), no skips. could be the egr. map sensor, o2 sensor, accelerater sensor, throttle positioning sensor, maf sensor, or what not. thats the general consensus. any one have this problem with some luck on fixing the problem? it is driving me crazy!!!
thanks
