Hooked ebpv back up mpg tanked????

Hey
I just got a 97 powerstroke and the previous owner had the ebpv plug and ebv and the flapper disconnected and wired open. I noticed the truck had a switch wired to make it an exhaust brake so I hooked it all back up except the ebv plug. My mileage went from 18 to 13. Would not having the ebv plugged in cause that. Everything seemed to function correctly. I like have the exhaust brake but ill disable it if I can't gain mileage. I will try plugging the ebv plug back in later. I just found out today what it was. Just trying to figure this out. New to diesels so sorry if this sounds dumb

I'm having difficulty following your description. Did the PO have the EBPV solenoid disconnected (electrically), the EBPV butterfly actuator rod disconnected (mechanically) and wired open? What about the EBP sensor (disconnected or remained connected)? Cheers!

You are correct. Everything was disconnected. I reconnected everything but the ebp (the one in front not the plug on the turbo that is plugged in. My mileage tanked. I really like the exhaust brake. I'm going to plug in the ebp but wondering if that could be the culpret.

I posted another thread, it might not actually be the ebp plug, i have no idea which plug it is. I cannot seem to see where it goes.
Where does this plug go??

You would want the EBP sensorplugged in (the PCM would generally like to see a signal from that sensor). The connector that is down by the turbo on the driver's side goes back to the EBPV solenoid which allows oil flow to the EBPV actuating cylider for the valve to operate. The exhaust brake switch should have been wired into that connector. The other side of that connector would go to the engine harness where the signal from the PCM would come from. Cheers!
