I would change the map sensor and the throttle position sensor and check the wiring while you're at it.

I know it can be frustrating, but try that first.

My girlfriend has a 2001 GMC Jimmy with a stock radio/cd player. after having the battery changed, the radio says loc and she is unable to "Unlock" it according to the manual. is there a trick? thank you...


you have to contact GM to get the unlock code which u can find online, just go to radiocode.com and they can help, it costs $7.95 or call your local gm dealer but they will probably tell u to come in and overcharge u!
