Ok, so it's about 7 years after the 5.0 swap in my Turbo Coupe. Cruise never worked after the motor swap until one day last spring, on a road trip from WI to CA, I pulled up on the clutch pedal with my foot (89 mustang pedal assembly, must have a weird notch that keeps the pedal from using the full travel) and turned on the cruise no problem. So I use it for the next 3-4 hrs when suddenly it grabs the throttle... 80...off button....90...brakes, BRAKES HARD...100...110...kill ignition, coast to a stop.
Ok, so I got the car stopped... But when I refire, the engine revs sky high... still grabbing. So I pull off the cable and continue with no cruise. Next day, reconnect, use cruise for 3-4 hrs... grabs, kill the motor.
So basically, it just grabs the accelerator and nothing will kill it... Not the off button, not the brake pedal, not the clutch pedal, not even turning the key to off!! To me, it doesn't sound electrical... so perhaps the servo is just bad, getting stuck somehow... I don't mind replacing parts but how can I test or be sure without just driving in the crazy CA traffic and waiting for it to happen again? Any ideas?
