Well I'm BACK , after getting my truck back on the road it did not last long enough for me . a few months ago I had gone through a long process of motor stalling when it got to operating temp. It ended up being a wiring repair done by dealership without my knowledge it fried the IPR also so fixed all that and for last couple months it has run great with no problems except brakes which I just finished front and rear a week ago. Two days before Christmas I was driving down highway when I noticed a change in the motor sound I pressed on throttle and not much power and no diesel sound . I quickly look at my ScanGauge and see the IPR was pegged at 84.7% so I change my route and cut thru high school headed to the house after about two miles at 84.7% it stalled in parking lot of high school two blocks from house. I walked home and gathered some tools and called to borrow dad's Jeep but did not get to start on it right away as I had shopping to do for family get together on the 24th the next day . After the gathering I went to truck and decided to disconnect the ICP first and see . Well it fired up but I had Jeep running to warm up in and lights shinning on truck to see . By the time I got Jeep secured and ice off my windshield the truck stalled and would not start . I went to house and rounded up the cheap ICP I bought for testing purposes and went back and installed that but I had run batteries down so now I had to pull batteries to take home and charge so another night in parking lot for truck. I got them charged up good and put them in this time I was reading to go as soon as it started . It fired up and I headed for the house and right as I turned into driveway it stalled. I have pulled and bench tested the IPR and its working fine so I went to dealership and bought a new ICP put it on and after a long cranking it started and I ran it 30 minutes in driveway but it would barely idle wanting to stall if I let off throttle completely . It was very sluggish as I throttled it up and seemed like turbo was not all there. Any ideas on this would be greatly appreciated , at this point I am going to air test it but don't think that is problem but I noticed that my base oil pressure was not coming up until after motor was running which it always came up with key on engine off before. I did check oil and its full . The other thing that was weird was the screen on IPR was still in hole when I removed the IPR I had to fish it out with needle nose pliers. And that screen was extra tight when I put in the IPR. Well thanks guys I hope I hear from you and Merry Christmas and Happy New Year to all.
