i have a low rpm stumble and i was told to clean the egr and maf. where is the egr and how do i clean it?

 

The EGR valve is located in the back of the intake manifold. It's a round metal part painted in black, mushroom looking, sort of.
Don't really know how to clean it, but if you're taking it off, might as well replace it with a new one.

 

dont waste your time with cleaning it.. if you have a 94 like you name says just get a block off plate from www.tpis.com for like 12 bucks and remove it.. i left my egr on there because i ddint feel like blocking the lines for it and there is a block off plate under it..
