well unpluged those no change.pressure is 60 @idel.could the throttle pedal cause anything like this?off idel its not as bad and pedal seems to be more sensitive than it has been.unpluges 3 of the 4 plugs on valve cover all 3 had the same effect on the idel.going to the zone to see if they can get the codes that setting the CEL.if not theres a guy with a snapon scanner i'll try and catch later on. after getting this truck and pulling with it yesterday and was really getting to like it more and then this happened

zone said no codes(this as the trucks running with check eng light on)
buddy with snapon scanner got 6 codes
1 was when i run it wide open and oil level got low in high pressure pump
the rest were showing fuel pressure but it did'nt say high or low.
it just showed volts and it was 3.75 i think he told me. now i did the bb thing 10 days ago would that have anything to do with it?
