Robo,

Check your accelator pedal down low beside the brake pedal.

There is a plastic piece that connects with the accelator (inside the passenger compart on the floor near the fire wall) that moves the pedal when the cruise control is engaged.

Mine was not put on properly after the evaporator was replaced and broken the first time I engaged by cruise.

New part was cheap from dealer. I installed it myself.

Hope this helps.
