Check Engine with 402 (1141?) Code (EGR staying open). Haynes has you do back flips. I checked for the obvious loose vac lines, electrical connections, can I just jumper some stuff (bypass) to see if it is the EGR valve. I checked many of the items, but I don't want to just start replacing parts. I put a vacuum on the EGR valve and it did what the Haynes manual said it should do. I have checked the VCV but it doesn't seem to hold the vacuum as long as it should, I have not checked the EGR gas temp sensor. Anyone with some experience with this? Thanks, Lenny in Austin
