My 02 impala is either maintaining or picks up speed after I let off the gas pedal. It's almost acting like the cruise control in on, so I pulled the fuse to the cruise. The problem stopped for a week or so, then started doing it again,and it does it randomly, .. any ideas on why it's doing this?
My Honda did this, I found it was the floor mat getting jammed against the gas pedal. Other than this it could be:
Worn out gas pedal cable, replace it.
Extremely dirty throttle body that is sticking, in this case clean the throttle body with approved throttle body spray cleaner.
