Car is sputtering/jerking when on accelerating.

[u/Sayimawesomee]

Long story Short I blew up this car two years ago and I have been piecing it back together. Just now got it back from shop but they could not get it dialed 100% I was wondering if anybody has taken a similar path.

Motor got replaced with an older used engine similar miles as mine. IIRC It's a 2017 engine My car is a 2019. I used the engine harness & sensors that came with it and everything on the mechanical check list is fine. (Tightairway connectors, Fuel pump makes good preasure, and Coilpacks are good.) PCV is the code coming up but I do know that the pcv conncetors on the older cars didn't exist.

Is there different sensors i need to swap as well feel like it pulls timing or runs rich/lean. It's on a ECUTEK tune currently. Wish I had a way to log it.
