MOTOR WONT IDLE WHEN HOT

1998 Ford Aerostar

Engine Mechanical problem
1998 Ford Aerostar 6 cyl Front Wheel Drive Automatic 85000 miles

WHEN THE MOTOR IS HOT IT DONT WANT TO START, WHEN IT STARTS IT DONT WANT TO IDLE
WHEN YOU PUT IT IN GEAR IT WANTS TO STALL
UNLESS YOU GIVE IT ALOT OF GAS THEN IT CHUGS
UNTIL ABOUT 5 TO 10 MPH. NO ENGINE LITE COMES ON. WHEN COLD IT WILL START AND RUN
FINE UNTIL IT GETS HOT. WOULD A TPS DO THIS
WITHOUT AN ENGINE LITE?

I would think the tps would set the light. Have you checked the egr valve? Vacuum leaks? Fuel pressure?
