at a loss.....need help asap!!

I'm stranded in albany right now with a truck that won't run......

Started acting funny, it was skipping or missing when I was driving it, but by the time I went to start it next, I couldn't even keep it above 1500 rpm. When I give it gas, at about 1000-1500 rpm it starts sputtering, shaking, and knocking really bad and half the time the check engine light comes on. As soon as the idle recovers, the light goes out. I tried to scan it with a tool capable of reading diesel codes but nothing is showing up. I changed the cps, as symptoms pointed to that. Also changed the fuel filter and cleaned and tightened the battery terminals. I'm screwed here and can't make it back to long island for work. Any insight anyone has would be greatly appreciated

I wonder if maybe the ICP sensor is going out. You can check it to see if there is oil inside the connector.

Not sure what type of work you are capable of ,given the circumstances.Have you thought about the Under Valve Cover harness?They tend to come loose.

The pic is one I found..it is the one where the arrow starts from...it is actually pointing to the bottom of the HPOP.Not the OIL line.

I pulled the connectors on both valve covers and checked the resistance, checked out good. I will try to take a look at that icp tomorrow, thanks for the info. If all else fails I'm going to have to leave the truck here and rent a car. I don't want it to come to that

I had symptoms like yours once, it would come and go and where the main wiring harness
crosses over the drivers side valve cover the harness had bare wires showing where it was rubbing on the valve cover. The wires were shorting out on the valve cover causing half the injectors not to fire. At first I thought it may be the uvc harness but they checked out , then I got lucky and found that small wear spot on the main harness. Two little bits of tape and it was fixed, good luck

Got the truck fixed, turned out to be the idm. Had to leave it upstate and hope to recover it this weekend. $700 all said and done, which is better than the $1500 the dealer wanted for the part alone
