Sputters and bucks, no power first 10 minutes

06 F-350

The sputtering isn't noticed when just driving around town but if I get on the interstate within the first 10 minutes of driving, it spits and sputters. It doesn't matter if I'm light on the throttle or foot all in it. Its worse going up a hill or under a slight load.

I got an SCT livewire and can now monitor some things but I don't know what to look for. Cel was on and showed #6 cylinder contribution and crank position sensor. The codes were cleared but nothing came back.

Crank sensor will create that issue. #6 injector is possible too.

I would check the connectors at the crank sensor and the ficm voltage when cold and while cranking.

Truck is in the shop getting a 4" turbo back exhaust put on. I'll check the readings when I get it back
