GMC Envoy Problem Report
GMC Envoy engine shuts down with defrost or A/C on
i had this problem for a while( my personal vehicle). The truck would go into reduce engine power mode at first. Turn the engine off and restarts with no prblem. I ignored it just didn't use defrost or A/C. Than as time went on(months)it got cold here in Philly and i needed my defrost.This time the truck shut off. turned off defrost and it started right up and ran normal. i looked for vacuum leaks. not many hoses to check. finally found advice via youtube to remove throttle body and clean it. I used Brakekleen and cleaned throttle plate very dirty. reinstalled and checked. Problem Fixed!!!! Quick!Easy!and Cheap! Thanks Youtube - Lucky Tech

engine will begin to die when A/C is on and car in or out of gear. I turn off the A/C and it runs fine and if it goes dead it will crank back up with no problem. - Visitor
