The 4.3L has an EGR valve right in front down below on the lower intake. it's a little tight, but very doable. It is held in by 2 or 3 bolts and has a gasket. yes, it can sometimes be cleaned depending on the severity of it. Use carb cleaner or some type of cleaning fluid and try that. You'll need to move the air ducting to the air cleaner out of the way.
We cleaned mine and used a less abrasive cleaner (can't remember what kind several years have passed) was told carb cleaner is to harsh, and a few small soft brushes, small round brushes worked great for the ports. Be careful while cleaning can damage ports. Also, it is easier to clean the TBI 4.3 EGR then the MPI Vortec (has alot smaller ports) We also poured sea foam in intake while blazer was running shut it off before it died and let sit for abt. 10mins. poured the rest in a full tank of gas. read instructions carefully on the can for amount to pour into intake. Started blazer then took for a nice drive. We did this abt. 5 years ago and not had a problem since. 250,000 miles. The EGR Valve is prone to plugging up with carb (seems 2 B worse in the Vortec). I run injector cleaner cleaner through my blazer every once in awhile. I hope this helps
