ok I'll try to make this short but Ive stumped 3 other techs around my town thus far with this truck.
Truck is a 2005 with 260k on it. original owner and impeccably maintained. Came in to have head gaskets done only as a preventative measure due to miles. Started and ran great before work was started, hot or cold. injectors were done 60k ago so owner decided to re-oring them and put them back in.
Tore the truck down and everything looked great. Put new heads on from UCF, ARP's, bullet proof water pump, bullet proof fan clutch adapter, new ford gasket's/ orings, glow plugs/harness's. noticed one injector missing fuel inlet screen so I replaced that injector which is now in #2
Truck already had bullet proof egr and oil cooler, & FICM so those were reused.
Installed a powermaxx stage 1 during reassembly.
Truck is now back together and running again but has a very slight miss. it starts hot or cold without hesitation. I have driven it roughly 30-40 miles since the work and the miss is staying the same. It idles smooth but if you rev it in park you can feel it in the steering wheel. just a slight da-da-da-da.
driving the truck WOT it runs great and is smooth however trying to maintain a speed at aprox 65-70 at 1800rpm the whole truck shakes and can be felt in the seat and wheel. mash the throttle and it smooths out.
tried swapping FICM's with no change. hooked up to IDS and ran power balence with no real conclusive result. 1,2,7,3 are +10 and 4,5,6,8 are -10
here is a video of the test. first at idle then rev in park and then a power brake. all with adaptive turned off. also passed relative compression and engine sounds normal cranking over, no speed up points.
