Rawze, I have been trying to get down to Atlanta area, but all the high paying loads are going out east and also to Arkansas from MN.

Even if I come, one of you would need to drive it for at least a hour or 2 in various driving conditions like stop and go, go through all gears few times and go up hills few times to be able to see all the weird things the engine does with full load.

Overall the truck runs great, pulls very well, gets good MPG, does not burn oil. It's just all the little thing it does every day is driving me crazy when My old truck ran smoothly and it had over a million miles on it, only thing in the motor that was new were injectors and turbo and water pump, everything else was original. It was a tired motor with a very noisy 10 speed. and it never complained compared to my like new motor that complains like a little brat.

I am just hoping for some guidance where to start looking and what tests to run until I am able to bring it to you or mr hags. I swear it is fueling issue that something in the fuel system is dying and not functioning 100% which is causing the engine to do all that little weird things. At low rpm in lower gears It sometimes does cut out completely for a split second. This is not at full throttle, its at part throttle.

When it does all other weird stuffs, All I have to do is just lift off a tiny bit then apply, usually first attempt all the problem go away. It only happens when boost is building up fast.

I am home right now and when I wake up I am going to hook up insite and check fuel pressure, then move the front actuator to the back to see if the problem moves. Also going to order new fuel shutoff solenoid as it is not that too expensive to do.
