My 1992 Ford F-150 won't start and idle when it is cold outside. If I push on the gas pedal ever so slightly it will start but won't idle. When the truck warms up to to the normal range on the thermostat I can then shut it off and it will run and idle fine. It has a 5.8L V8 EFI motor.

hELLO , THE FIRST STEP YOU SHOULD TAKE IS TO CHECK FUEL PRESSURE , HOWEVER IT IS PROBABLY OK IF IT RUNS FINE WHEN IT IS WARMED UP .. TAKE THE AIR SNORKLE OFF THE THROTTLE BODY AND LOOK INSIDE THE THROTTLE BODY WITH THROTTLE PLATE FULLY OPEN ,, IF IT IS ALL GUMMED UP CLEAN IT OUT WITH A SMLALL TOOOTH BRUSH AND SOME INTAKE CLEANER,, IF THAT DOES NOT CORRECT THE PROBLEM , THEN I WOULD PROBABLY REPLACE THE IAC MOTOR ( IDLE AIR CONTROL MOTOR)
