Ok so I just checked out the EGR and I can move the diaphram up and down just fine with a screw driver, and theres suction in the vaccume line, so that can't be the issue. Any other ideas? I've heard some people say the sensor goes bad sometimes on these so would that cause the EGR to have insufficient flow?
The motor started running real bad last night. Seems like at a cold start it runs fine for 10 minutes, then out of nowhere acts like its being flooded out and starts bogging way down and almost stalls out. You can even smell how rich the exhaust is.
