1993 blazer rough idle.. sort of
Hi I just bought a 93 blazer 4.3 HO W code Blazer. THe thing runs great and only has 61k miles on it. Anyway when at idle the thing idles kind of rough and change RPM's while doing so.(mostly in Park) It also starts a little hard when it has been driven for a while. I'm wondering if I have an EGR valve problem or possibly something else. Engine sounds healthy and runs great and really moves down the road. Now I'm also wondering if it could be an exhaust problem. No sulphur smell or gas smells. THere is carbon in the exhaust pipe.
THanks for the help in advance and hopefully I can get this thing running absolutely perfect.
