jLevin, did you replace the whole thing, or part of it? Was it an easy fix? I had the CEL coded, and it came back as "insufficient flow" in the EGR valve. The dealers want to charge you for the scan even after you have told them what the problem was diagnosed as. I guess they don't want you knowing where the problem lies so that they can charge you all over for it again. Is the EGR something that any ASE certified mechanic shop can fix? Thank you for your replies, I will heed them all!
