I have a 03 Sierra 1500. I was driving and out of no where i lost all power to the throttle, and warning came up saying Reduce Engine Power. I would push the gas pedal and it wouldnt do anything, not even rev. after turning off the truck for a few minutes i was able to drive the truck with no problem but with the check engine light on. 10 minutes into driving the check engine light turned off. After a two months of no problems since then it happened again. Do i need to replace the throttle body?
