Re: 1995 GMC Jimmy rough idle small loss in pwr
sounds like an EGR problem. Common to find carbon chunks interfering with the plunger. Mine is doing the same thing. When I get the time to get to it, I'm going to put one of the screens available from Carquest in & hopefully will eliminate this problem once & for all.
