F150 IDLE PROBLEMS

1999 Ford F-150

Engine Mechanical problem
1999 Ford F150 6 cyl Two Wheel Drive Manual 100112 miles

THE IDLE IS REMAINING HIGH EVEN WHEN CLUTH IS ENGAGED. THE ONLY TIME THAT IT IDLES CORRECTLY IS A FULL STOP. IT IS NOT THE THROTTLE CONTROL SENSOR, I REPLACED THAT AND IT IS STILL THE SAME

Check your PCV valve and clean the IAC module and the inside of the throttle body.

That should clean up your problem.
