lossing cylinders at random times

[brian89]

i have a 2000 f250 with 185k miles, recently on a trip from florida to pa i was driving and it all of a sudden started acting like it was running out of fuel, but i still had almost a full tank, when i stopped it just sat there and loped. when i tried to hit the accelerator and move a little bit, it had no power at all, after about 5 minutes of sitting there and loping and me scratching my head it started running fine again like nothing was wrong? i had just started running diesel kleen thru it and i thought that was the problem, so i stopped and have run a whole tank of fuel thru and yet again today it did the same thing to me? some help on what could be going on would be much appreciated

[brian89]

what would be wrong with it? is there a short or an open somewhere? or is it just going bad? and how much of your money would you put on a new one?

Symptoms of your truck describes exactly issues I have with my truck. What I have done so far: First I checked for codes, no issue there, no codes. Replaced CPS part from NAPA, symptoms still shows. Look under drivers side valve cover and looks like the previous owner already put the quarter(Coin) fix on the wiring harness. I didn't look under the passenger side Im assuming the quarter fix already apply on that side. Pull the ICP, very clean and when I ran the truck with the ICP pulled, symptoms still shows. Repaired the IPR with the repair kit and the problem still exist. PULLING HAIRS RIGHT NOW.... any ideas where should I go from here? I really appreciate it.

you guys need to o a buzz test and then read the icp pressures and percentage

I forgot to mentioned that when I was repairing my IPR which I have to drain out the HPOP reservoir it only contain half a quart. Then I look further in the engine bay and notice oil accumulated in the middle and the end of the block. I had tried to trace it thinking it was coming from the IPR(original IPR was still in) but it looks like it was coming from the passenger side of the block. It was wet starting from the valve cover streaming down toward the V area. I think this was a mistake in my part and I completely ignore it, I should fix and trace this leak first, it probably coming from the high pressure oil line. What you guys think?

Ok so when my truck starts acting up, shaking, no power, lost cylinders, how do i get it to run like it should? Or do i just let it sit and wait?

What do you mean by coin "quarter" trick?
