ALRIGHT THE CAR RUNS NICELY WHEN I FIRST START IT UP AND RUN IT BUT ONCE IT STARTS WARMING UP I BEGINS TO HESITATE WHEN I KEEP THE THROTTLE IN THE SAME POSITION IT WILL STUMBLE AND LOOSE POWER THEN REGAIN IF IM IN FIRST GEAR IT WILL HESSITATE AND THEN START BURNING OUT. IS THERE ANY WAY TO TEST THE THROTTLE POSITION SENSOR. I JUST SET IT AND PROBLEM DID NOT GO AWAY. COULD THE EGR SOLENOID DO THIS???

first off don't use all caps.
second, have you done a tune up on it. plugs, wires, cap, rotor? of not i would almost put money on your ignition system being the problem.
it could be the throttle posision sensor but if you just set it try testing it by running it from closed to open slowly and there should be no big jumps in the reading
i don't know about the egr solinoid.

edit
i missed you said it runs fine when cold. it could still be the pulgs but try the o2 sensor since it might be a closed loop operation problem

yes i did replace all of those things along with the TPS sorry bout all caps wont happen again HAHAH
it might be my wires they did get a little scorched and ill try that O2 sensor too.

DOES IT REALLY MATTER IF SOMEONE USES ALL CAPS, DONT GIVE HIM A HARD TIME ABOUT IT, ITS NO BIG DEAL...

On the internet, all caps means you are shouting.
