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.
