P0476 code

Truck is '95 F350 cc A/T 125,XXX and has sat for a while. I ran codes and saw the P0476 code but she seem to run ok but sluggish. It had exhaust leak at cat so I removed dp, cat and muff and replaced with 3" dp and straight pipe. Truck stills throws P0476 and seems to be struggling when giving it WOT, but not all the time, but most of time. The A/E when plugged up to live streaming shows 38.XX-42.XX on the EBPV and my '96 in signature reads only 14+\- when driving.

I own 3 of these OBS and helped a few friends out and never saw this code. Tests, KOEO, pass, KOER, the EBPV functions but throws P 0476. I have cleared codes and checked after driving and finding her intermittent but mostly bogging down, P0476 when returning. Inj. buzz test pass, contribution test, pass.

Any suggestions? Thanks for looking.

If you have the wire unplugged and know its not closing, I wouldn't worry about it.

If it's bogging down try unhooking the ebpv and wiring the flapper open. See if that helps with the bogging.
