CARBURETOR IDLE CAM STICKING

1986 Pontiac Parisienne

Engine Performance problem
1986 Pontiac Parisienne V8 Two Wheel Drive Automatic 250000 miles

Idle cam sticks on an E4MC carburetor so that the engine does not idle down when warmed up. No amount of tapping accelerator helps. Choke pull off has been replaced and works fine. Any suggestions appreciated. Thanks - Tom

Take some choke cleaner and spray all around the cam. Then open the throttle up abit and physically move it up and down and spray with choke cleaner once more. Do this until it moves freely. That should cure it.
