Engine Mechanical problem
1978 Ford F150 V8 Two Wheel Drive Automatic 197000 miles
When accelerating from a dead stop, (like pulling out into traffic) the throttle stays open and and won't return when I let off the pedal so I have to either throw it into neutral or turn the key off. It only does this in drive. I can make this happen while sitting in drive with the brakes applied and then slowly giving it gas and then the throttle "catches". There are no throttle sticking problems with this holley 2 barrel carb. The return spring is tight. While in park there are no problems with it ever catching or stayng open. Also when cruising down the road I can accelerate suddenly with no problems and shifting is fine. The kickdown rod seems to be working properly (WOT). I have made adjustments to the vacuum modulator and the transmission responds like it should to these adjustments. Obviously this is a dangerous situation that I would like to get repaired, just not sure what. Thank You.
have the same problem?
