Re: I need a smart GM mechanic\'s help
JimR,
I haven't read the entire thread, but my 95 Blazer with the 4.3 was running like crap also. I bought it brand new, and it only has 60,000 miles on it now.
I took my EGR valve out and sprayed it with carb cleaner. It was all carboned up, and the spray loosened it up. I put it back in and it is running good again. /forums/images/graemlins/laugh.gif
