This happened last night with my 1996 f350 Powerstroke I was towing a pretty heavy load and lost all power and it started blowing tons of blue smoke I had to poll off the road. Well I tried starting again and nothing but blue smoke and it would not rev over 2000 rpm it would take me like 2 miles to just get up to 50 and no check engine light.
Well I made it to my exit only able to do 50mph and when I was decelerating (down shifting) I got a check engine light and then all the power came back and no more smoke.
Well today It will do the same thing No power, lots of smoke, and will not go over 2000 rpm in till I decelerate and get the check engine light. then it runs like normal with no smoke.
I can use a scanner on Monday to get the code but the last code I was getting was the ICP sensor and Turbo boost sensor high input code.
The truck is stock with 275k on it.
when standing on the bumper looking striaght down on the motor it will be in the valley slightly towards the drivers side, has 2 wires coming out of it.
Ok just scanned it with a modis scanner hear are the codes.
P1298 IDM Fault
P1211 ICP Not Controllable - Pressure Abow/Below Desired
P0471 Exhaust Back Pressure Sensor Circuit Performance
P0476 Exhaust Pressure Control Valve Performance
Injecter pressure was 750psi at idle and 815 at 2000 rpm if that helps.
