I'm getting an egr fault code on 93 2.5L tbi. Idle is somewhat rough, as usual with this code. However, while idling, if I disconnect either the vacuum line to the egr or the electrical connector to it, the idle gets much worse. This seems to indicate that the egr valve is functioning. I have removed it, cleaned it with carb cleaner and reinstalled with a new gasket, making sure to clean the mating surfaces. There was no buildup of carbon at all, and the car has only been on the road with this setup for a few months anyway.
Any thoughts?
Thanks
