The EGR valve? Is one of the reasons my 1998 mazda 626 won't pass emissions. I need to find the egr and maybe what it looks like. Is it electrical, vacume controledor what. Is it posible that the electronic(if it is electrical) be ok and maybe yhe vacume could just clogged. Eather way would it also make the idle(it changes back and forth to slower to faster idle) when it slows it idles rough.
have the same problem?
