Stiff gas pedal

Seems like my 2000 Ford E-250 5.4's gas pedal sticks at the closed position, and then fine once depressed. I don't remember it being like this before, but lately I have noticed in traffic. Anyone have such a experience?

Re: Stiff gas pedal

I had a car that did that. Turns out it was a broken motor mount and the entire motor was moving, which caused the throttle linkage to move funny....

Another time I rented a vw thing in the Caribbean.. The throttle cable was rusty. Boy was that exciting, learning to drive on the left side of the road with a sticky throttle...

That's all I got

Re: Stiff gas pedal

Start by checking the cable running from the gas pedal to the throttle body---make sure its not binding. Possible issues would include an accidental bending or kinking of that cable although your symptoms suggest this happens just once during each drive cycle.

Disconnect that cable from the throttle body, actuate the TB by hand to make sure its not "hanging up", that it moves freely both opening and closing.

With the cable detached check to pedal's operation to make sure something inside the cabin hasn't become lodged somewhere in its pivots etc.

The accelerator pedal system is fairly simple, pretty much maintenance free for the most part----this is certainly an odd situation. Best part is nothing is too expensive should replacement parts be needed.

Please let us know what you find---for our mental data bases.

Re: Stiff gas pedal

It's also possible the throttle body needs cleaning. After a while, oil vapor from the PVC system can end up as a layer of film on the throttle body, causing some stiction.

Re: Stiff gas pedal

That's a good point CarringB!

I was about to suggest a good preventative maintenance step of TB cleaning but wasn't sure if Herr Stiggs was familiar with the procedure.

Re: Stiff gas pedal

I am going to clean the throttle body this weekend and see if that helps out
