99 E150 4.2 V6 EGR code
I'm getting the dreaded P0401 EGR insufficient flow code on my 99 E150 4.2. I've cleaned the EGR passages, replaced the DPFE and hoses, and the EGR valve. I'm STILL getting the dreaded P0401 EGR insufficient flow code. What else could I have missed? The engine only has 8K miles on it.

Changed the EGR vacuum solenoid and the cel stayed off for 20-30 miles but then came back on again. I talked to some master technicians and they said it's probably the ecu. They are known for frying and causing EGR code issues. :face palm, shakes head:
