My EGR valve stuck on my '90 Mustang. All I did was to remove it and use some spray Wynns Carb Cleaner to remove all the carbon deposits. That was a year ago and the engine has been smooth as silk from then on. It's an easy job - make sure when you put it back that the connections are clean and tight and the gaskets are leak-proof.

So go ahead, clean it - it's cheaper than a new one!

Also, be very careful with any chemical that you use to clean it - most are harmful if you breath them in.
