And then you have the EGR on my car. ---- thing keeps lighting the SES light, annoying the piss out of me. Three different solinoids, and the light still comes on. New vacumn line, and the light still comes on. New valve, and the light still comes on. Bad wiring? Bad connectors? Only God knows at this point. I've done tests by the book, and nothing relevent can be determined. aaarrrrrrrrrg.
