vibrating gas pedal

anybody had / have this ? its almost as if i can feel the engine detonating , through the pedal . only happens when the engine is running so im assuming its something gettin transfered through the cable , and not the cable gettin caught up on something ..

i cant figure it out it only happens under certain throttle percentages too. its not across the whole motion of the gas pedal . id say the first 60% of pedal movement i can feel it . then it goes away from there on up to 100% throttle. ..

maybe somebody down here in FL can drive it sometime and check it out .

I get the same thing. It gets worse over time too. I've been meaning to mess around with the pedal to make it stop but I keep forgetting (for 3 years now).

I've never felt detonation through the pedal though, that is a new one by me.

its not detonating though . thats the closest thing i could use to describe it .. it feels like ticking or vibrating .. like im running a gas pedal that has relays on it and they are clicking on and off . its really weird . lets say at 30% throttle i feel a "tap" on the gas pedal .. no matter if im accelerating or decelerating , i get that same "tap" at that exact same spot or throttle percentage every time ..

using that same scenario , if i pump the pedal between 28 and 32 % , ill feel the pedal click each time i push and release the pedal across that 30% threshold ..

i know i sound crazy but you have to feel it to understand it . i really dont know any other way to describe it .

Johnny E., it sounds like your problem is different that what everyone else has chimed in with. It also sounds like you've addressed the issue. I was going to recommend lubricating and checking your throttle cable and linkage. Also cleaning the throttle body could help out. My throttle was sticking shut, so I removed it, cleaned it, and went the extra mile to adjust the set screw to keep the plate out a little further. I was thinking that your butterfly was sticking inside the throttle body, or the linkage on the outside of the throttle body was causing a problem.

As far as the throttle pedal buzzing, I get the same thing too. It happens only under cruise control, and only when the cruise dials in more throttle when encountering an incline. So, the buzzing is caused by a resonance as created by the greater engine load. On flat terrain, there is no buzzing.

I have also noticed that when I lay my foot on the pedal (barely touching it) the buzzing goes away. This leads me to believe that the noise is coming from the pivot between the throttle pedal and the pedal arm. I don't think it's between the pedal arm and the throttle cable.

I haven't done anything about it yet, but I'm going to start with some lithium grease on the throttle pedal pivot.

thanks for chiming in , im going to check the places you mentioned as well . maybe i can solve the last bit of it with that .

I hope that does it for you. Since so many people seem to have the same problem, be sure to let us know how it works!
