Engine Performance problem
1991 GMC Sierra 6 cyl Two Wheel Drive Automatic
When I start my truck in the morning during the hot weather season the idle speed varies up and down and when I shift into reverse the truck will alternately try to kill and then surge like it wants to run away. I have changed just about every sensor and the egr valve and computer. I had the truck in a shop but they could not find the problem. I have seen similar complaints on Two Car Pros site but the solution was not mentioned. 10
have the same problem?
