It may clear itself after a few miles, or you can clear it with an obd2 reader, or go to like autozone or partsamerica and they will for you.

 

Awesome. Thank you very much. I used both write ups today and can't wait to take my blazer on a roadie!

 

My 92 blazer has about 211,000 miles on it and the EGR valve has never been replaced or cleaned. I was going to clean it but would it be a better idea to just buy a new one?

 

Any idea if the EGR valve would be around the same spot as in picture in a 2002 blazer 4.3 4x4

thanks Mike

 

If it is a late model 2002, you do not have an EGR valve. If it is not in that location, you have the later model.

 

thanks swartlkk

Was going crazy trying to look for it, went to advanced-auto because i had check engine light on, so this girl red it for me n she said it was the "EGR code", but didn't tell me any specific number or code, and said it could be a lose wire or I need a new gasket for EGR, the truck runs great until a week when I was a red light than I started driving again and it ideled faster, "almost sound" like I shifted the gears but just in the idel not actual gears, any ideas on what it could be?

thanks Mike

 

Why not just plug in the EGR when you run the engine? This could be done right after you remove it or when you're done cleaning it. Worked for me, no CEL light.

 

so if we don't have an EGR valve, what do we have?
Chevy did away with it or re-routes the exhaust gases another way?

 

A big thank you for this article. My 95 is definitely running better as a result. The MAF is next, but I'll need to find it on the 95. Its not in the same spot as on the 96 you took pictures of.

 

I'll save you some time. A 95 doesn't have a MAF sensor.
