2004 GMC Envoy
Engine Mechanical problem
2004 GMC Envoy 6 cyl Two Wheel Drive Automatic 78000 miles
I have a 2004 GMC Envoy XUV. I have noticed that sometimes while sitting at the light with the AC running or not running, I will loose power and the car shut off. I have changed my fuel filter and starting using 89% octane gasoline to see that that will help but it didn't. What do you think the problem may be?

Has the check engine light come on? Have you checked fuel pump pressure? Have you checcked for vacuum leaks?
