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 code. What else could I have missed? The engine only has 8K miles on it.

Welcome to the site..

Passages at the throttle body are clear/cleaned?

Could it be an ECU problem?
