Hello I need to know where the EGR-Valve is located and also can it be cleaned to make it work again or does it have to be replaced and how much does it usually cost ? Thanks for any info. Jim

There should be a data plate on the radiator cross beam that shows the location. On the SL1, it's on the driver's side, mid-block, under air intake duct, looks like an OJ can with a wire harness connected to it's top.Yes, the air ports and valve seat can be cleaned out for the carbon build up.

on the 95 sc2, it is directly to the right of the oil filler cap, its a tall black cylinder. clean it with carb and choke cleaner and replace the gasket

Thanks Guys for the replies I will check it out this coming weekend. Jim
