IS this fully open or just part open? Also I can't access my data base just now, so can you advise if cable throttle or drive by wire, I am thinking it will be cable, just want to be sure.

Have you unhooked the cables and see if the throttle sets back to idle? If so one of the cables will be sticking if not the throttle body will be the problem and possibly the TPI sensor may be stuck.

The throttle opener is not adjustable, notes say the throttle body should be replaced, see pic for this from Mitchell 1, I would still get a mechanic to check this first hand to confirm the diagnosis.

Is it the IAC or throttle plate you are referring to?
