| Cruise control cables jamming throttles open on fleet of 2001-2004 ford f350 utility body trucks with 6.8l v10 engines. occurring about january 25 2006. another unit had the accelerator jam wide open. unit burned up the braking components from driving to our repair shop. discovered the cruise control cable end guiding tube would fold down onto the intake manifold and jam the throttle wide open. 2001 through 2003 units affected currently had these cables disconnected and had no further recurrences. occurring january 22, 2007, also had the accelerator jam wide open. a newer 2004 unit, this one had an accident running into a wall. again, discovered the cruise control cable end guiding tube would fold down onto the intake manifold and jam the throttle wide open. we will be looking for units affected and will disconnected their cables until a remedy is available. we speculate this can be caused by these combination of these factors: 1) influenced by driving conditions that promote rapid cycling from wider throttle openings followed by the immediate closure of the throttle; as with stop and go driving demands. 2) cruise control cable end guide component drooping with higher under hood engine temperatures. this allows the cable guiding sleeves to not correctly overlap and prevent it from freely sliding through. this forces the cable guide sleeve down to jam onto the manifold. 3) harmonic frequency amplification of combined vibrations. vibrations generated from the vehicle pitching from the road and acceleration and deceleration motions. the kinetic energy of the moving cruise control cable components tries to continue it's forward opening motion when it is suddenly reversed with the throttle closure. any excess cable within the guiding sleeve may still be moving in the opposite direction upon throttle closure; possibly jamming inside the sleeve. *jb | |||
