Engine Performance problem
1995 GMC Jimmy 6 cyl Four Wheel Drive Automatic 188000 miles
I am having a problem with carbon chunks getting into the egr valve. I have had to have the valve pulled off about 3 times in the last 3 days and each time the problem is that there is a chunk of carbon holding the valve open. I was wondering if there is any thing I can do to fix this problem, and what is the proper way to pull the egr valve off.
