Pulled off the throttle body and just like all the other posts on this board. Both holes were 101% clogged. Having seen how they bored the hole I now see why this happens. They have a poor porting from the long shaft from the EGR valve to the two ports into the elbow. Mine was clogged to the point of the crap sticking 1/4" out of the hole furtherest from the EGR valve. Then it all was backed up past the closer hole (about 1.5") I placed about 3/4 of can of Intake cleaner into the holes (literally tilted the hole assembly to let the stuff sit in there for about 30 minutes) Then came out and dumped it and the whole thing was Whistle clean. (BTW prior to this I replaced the DPFE module which initially cleared the SES light for P0401 and P0133, but did not solve the sputtering)
Took it out for a drive and no more hesitation, sputtering, when going up hills with about 10-20% throttle.
Thank you board for the advice and help
