Viewing 1 - 2 of 2 problem details
Started when my ignition wouldn't turn off and had to keep it running. At same time AC went out on driver side. Only blows hot air. Had to stick a pin in the ignition reset to eject key. Had whole ignition column replaced and now next to the throttle body is a clicking sound. Are service engine soon and reduced engine power light keeps going on but after warming up.. reduced engine power went off and ran fine but now it will start but wont rev for power.
Envoy wouldnt start replaced battery wasnt that had to have it towed mechanic said was fuel pum. Going to cost me $820 parts and labor. Ive spent so much money never again buy an envoy
