this is a real stab in the dark but might help ? on the bottom of the throttle pedal is a button that clicks when you press the throttle to the floor to over ride limiter and cruise, check its operation and wiring.. may be this is what the faults are refereing to ...Ok, here I am with the diagnostics... Under: Engine ECU it shows two faults:
Permanent fault. Vehicle speed limitation Short-circuit to positive or circuit open
Permanent fault. Vehicle speed limitation Coherence of the sensor voltage
Also it shows P1614 as the ECU fault code.
My lower ball joint is due for replacement. Could it be connected to this problem somehow?
Thanks a lot.
