Well, thanks, but no, that's not it. Also, I tested the EGR Valve and with my breath I can actuate the solenoid - open and closes freely. I am beginning to think the vsv is not doing the same thing. I closed/opened it per my Haynes by shorting two test terminals and the MIL stayed off for over 20 miles - contantly going through drive cycles. I thought it was fixed. So maybe the new vsv is sticking open or closed. So maddening. I am waiting for a replacement MAP now - this will make a final dianosis more definitive. Do you know a simple test to check open/closed egr vsv?
