Question about 1995 GMC Jimmy
My 94 Jimmy had similar problems, until the dirty EGR valve was replaced. We tried a million things, first. But the improvement with the new EGR valve has HUGE.

On mine I usually pulled the old EGR and removed the carbon; it's a very common thing on the 4.3L V6 with TBI- chunks of carbon from a design flaw are the cause, but usually the EGR can be cleaned without completely replacing it...

Sounds like the EGR valve is not working because of excess carbon build up.
