1 UVCH unplugged truck runs better.
94' f250 7.3 powerstroke.
Ok few weeks ago i started my truck and it started fine, ran fine. after warm up i started going forward and it started running like **** and threw the CEL. Ive been reading on here about the UVCH. Everyone on here with that issue seems to have no change when it is unplugged or the truck dies. Mine started running better and the CEL went out when i unplugged drivers front plug. Its not 100% but alot better than with it plugged in.
Anyone know how to diagnose this problem or what it is?
Drivers side bank had oil in the UVCH plugs.
