2001 Ford F-150 - 6 cylinder truck. When I fully depress the gas pedal it sticks down. I have to kill the engine and pull over. AS soon as the engine turns off the gas pedal comes back up and it only happens when I floor it (driving on freeway ect). Can you help? Much appreciated. Cole

 

Have you checked the throttle return spring?

 

Check the return spring,and clean the throttle body...

 

thx for the reply. no i have not yet checked the throttle return spring. is that easy to get to ?

 

Should be on the side of the Throttle body,around the throttle plate shaft.Also...The Throttle body "innards" can get gummed up causing the throttle plate to get stuck...

 

as soon as the enigine is off it works fine . kinda like the curise control takes over and curise contol is off.

 

Check the throttle body spring and make sure it is still there. You can also try disconnecting the cruise control throttle cable and see if it is indeed the cruise control for whatever reason. I have a feeling that it is the throttle return spring though.

 

OK thanks alot for both of your input. Will try that and go from there.
