Have had this happen periodically in my
Remove the air cleaner duct hose.Take some gumout spray and clean the throttle plate. (large flapper)They will build up with a black gum which causes the pedal to stick off idle. If it sticks at speed it may be a bad cable... get it replaced.
The accelerator pedal. Also known as a gas pedal.
Your cabel, the one that is conected to your throttle may needed to be looked at.
If its fuel injected i have no idea. But if not just watch the motions and something will either be rubbing or one of the springs are worn out.
One of the main causes of feeling a vibration in the gas pedal is engine vibration. The vibration from the engine causes the accelerator cable or linkage to vibrate and the vibration can be felt in the gas pedal. Check with a mechanic to be sure.
Found out that I had an exposed wire lying on the arm of the gas pedal.
The pedal needs to be greased with good ole WD-40 where the pedal goes into the firewall.
A person pressing the gas pedal.
If the gas pedal is sticking on a 1980 Chevy, it is possible that the cable is wearing out. Check for slack in the cable. There could also be dirt on the pedal itself that is causing it to stick.
you probably have a worn out throttle cable. replace as soon as possible before you have a wreck. they are usually $20.-30 for new one.
Take it to a mechanic ASAP. This is very dangerous. a cause of is the throttle cable fraying replace the throttle cable.
It is when after you step on the gas pedal and then let off, the pedal does not return to normal position. The result is extremely unexpected and dangerous.
