GMC Troubleshooting Questions? Ask a Mechanic for Answers
Hi there, I am Cam. Can you tell me your first name?IS there anything physically stopping the throttle from moving properly?Did you relearn the throttle position? Did you reset it?Take the battery cables off the battery, hold the ends together for 10 seconds then attach them to the battery and see what happens. This will reset the whole vehicle.If you have 2 batteries, then remove both and touch only one set.
