Message: [QUOTE="David N, post: 681240, member: 70"] Okay. So as most of you know I blew my PMR motor up couple months back. Put in a 120k mile "takeout" motor from a 1999. Pretty straight forward. Swapped every sensor from the old motor to new motor. Along with some new parts. Injectors were reflowed by Full Force and checked out 100%. Bigger nozzles were installed as well. Well I got AE right after this engine blew, and ever since it seems to have a miss. It always throws a contribution code for #3 and #8. One time a couple nights back, I got a code for IDM failure (I can't remember the exact code). But I have yet to get that again. I have the stock IDM. And yesterday I tried a new blue international CPS, with 2 shims. Now when I start the truck, it idles choppy for a second, but them clears up. I do believe I have a slight miss though, all the way through the RPM range. So what is next? A new IDM? Also ICP sensor has over 60k miles, along with IPR sensor. I have not replaced them in the 3 years I have had the truck. And I will admit my HPOP is VERY week. WOT runs result in pressure dropping to 1800psi and 75% duty cycle. Any thoughts on the miss?
