I have a 95 GC LTD with the 5.2 . I recently changed the cap and rotor . It ran great afterwards but noticed that at highway speeds upon releasing the pedal to coast at say 60 mph , I would get erratic hesitation and bucking. If I am depressing the pedal , its fine . If I take my foot completely of the pedal, its fine . Only at the midway point of the pedal does this occur ie-- coasting while lightly fearthering the pedal. Hoses and wires all appear to be in good shape . Any help would be APPREC.

mine used to do that until i changed the speed sensor. then it was fine.
