So today i had the batteries load tested and they both checked out good. The issue I am having seems to have morphed a bit. Now when first accelerating it runs clean up to about 2200rpm then starts crapping out and blowing blue smoke. let off the pedal and it cleans up shifts and moves on, I can now begin to accelerate more heavily and by the time it hits 3rd I can go full on with good acceleration. Once in O.D. it begins to shutter when on a slight incline. BUT, decrease foot pressure or increase foot pressure and the shuttering stops. I have pulled all recent codes, the only ones now showing are EGR codes, but that is unplugged. I also am getting a fuel level sensor A and a couple codes from the overhead trip computer, it doesnt work so it's tossing codes. There are NO tranny codes at all. I did a contribution test and all is well there as well as an injector buzz test and again all is well. The ICP is registering the same pressure as the desired pressure, with a few pounds one way or the other. I have lost no oil or coolant and the degas bottle has not burped. tranny fluid is very clean and full also. I am STUMPED

 

Another guy had similar running issues. Punched out the cat and that took care of it.

 

I think I saw that post. Worth trying I suppose.
