Got an 11 Lml in the shop. Cp4 blew up a year or so ago. Cp3 swap and tuning got it going again (original injectors) cleaned all lines etc.
Always threw low rail under hard pulls. No big deal it's a grandpa truck.
Installed fass 95 two weeks ago as low rail was getting worse. Solved low rail (well bandaid) week later starts this misfire, shudder, rattle, smother out shit.
Well figure it's time for injectors. Brand new set from lds. Same problem.
Rail pressure and data look perfect. Changed tunes for giggles same thing.
It acts like it's getting fuel pulled away from it by something. Can't prove it. Truck will do it under medium load, hard load, brake torque in the shop. Always happens about 2300+ rpm.
Kinda lost on what to do with it. I havnt messed with the tcm any. Cannot see anything data wise that's a problem. I do have another 11 tcm on the shelf that had an intermittent problem for loss of power or something, so I'm tempted to plug it in.
Any ideas? Anyone have this issue?
