loss of power

I have a 96 model f350 2wheel drive dually with the 7.3 diesel 216000 miles OK i will try to explain the codition.It will be running just fine then it will start acting like it loss power on a cylinder and then it gets real week and it seems if you run the tach up to 2500- 2800 rpm in 1 2 3 gears it will eventually straighten out or you can stop get back in the truck in 5 min. or 2 hours later and it may not do it again the rest of the day and somedays it doesnt do it at all You can put the truck in neutral run the R.P.M up to abought 2800 rpm and it will white smoke and miss.sorry for the long post just trying to cover it all . newbie here and my first ford diesel Thanks

Hmmm, is the check engine light on?? When was the last time you changed the oil and what brand of oil did you use??

Well, sounds like to me that it is a sensor going bad or a couple of wires shorting together.

First thing is to look at the UVC (under valve cover) harness, if you look at the valve covers you will see 2 plugs on each cover, in the valley of the motor, unplug these very carefully and look at the pins on the plugs and see if any are burnt. If so replace them.

Then start checking your sensors, the ones that come to mind are the ICP sensor, which is on the drivers side, towards the front, it may have melted some wires together in there, unplug it and see if it helps.

My 95 owners manual only tells you that the fuse panel is at the lower left edge of the instrument panel. Pull on the handle to disengage the fasteners. Hope this helps
