Having problems with your 1990 Buick Riviera ?
Can I replace my EGR Valve on my own or should I have it done at a shop
Depends on how mechanical you are. You will have to get at it, unbolt it, clean the gasket surfaces, install new gasket and bolt the thing in. Bust the head off a bolt, and you are in deep poop unless you are good at extractions. Look at a parts store website to see what it looks like, then find it on your engine. If getting to it is fairly straighforward, go for it, on the other hand if you have to pull a bunch of other stuff off just to get started leave it to a pro.
