    2011 Tundra 5.7 TRD off-road
    Howdy I have a 2011 tundra 4X4 with the 5.7 flex fuel, I snapped a valve spring and grenaded the engine and decided it was best to replace it. I picked up an engine from a 2WD 2008 5.7 tundra non-flex fuel. It was the only engine I could find remotely local, was well maintained and looks brand new inside. I read that the engine would swap just fine, which it did for anyone wondering if it’s possible. But now i’m faced with some pretty interesting problems and i’m stumped

    i’ll go ahead and list those out here:

    P0017:
    Crankshaft Position - Camshaft
    Position Correlation (Bank 1 Sensor B)

    P0018: Crankshaft Position - Camshaft Position Correlation (Bank 2 Sensor A)

    P0019: Crankshaft Position - Camshaft Position Correlation (Bank 2 Sensor B)

    P0393: Camshaft Position Sensor "B" Circuit High Input (Bank 2)

    P0102: Mass Or Volume Air Flow Circuit Low Input

    P0113: Intake Air Temperature circuit High Input

    P0358: Ignition Coil "H" Primary/Secondary Circuit

    I tore the replacement engine down after buying it and freshened it up with new timing chain tensioners, cam tower reseal, all new valve springs, spark plugs, PCV valve, front main seal, alternator, starter, crankshaft position sensor, exhaust header gaskets, intake manifold gaskets, valve cover gaskets, spark plug tube seals, and all the little gaskets between here and there. The timing chain showed no signs of stretch so I didn’t replace it and the guides looked brand new.

    I had misfires on all 4 cylinders on the passenger side upon first start up, which seemed to fix itself after messing with it for a day or two and cleaning the grounds on the negative battery terminal to the body, the passenger side valve cover, and the connection the the noise canceling thing on the passenger side valve cover.

    I also changed the mass airflow sensor to the one from my old engine with no result (this may be because I haven’t completed a full drive cycle, those codes are permanent) looking at the live graph, it seems like it’s normal. Flat at idle, increases when giving it some throttle.

    Just today I gave it the first test drive after all my work and it has a very gentle vibration at idle, nothing too crazy but more than normal. During my drive it seems a little gutless, and the power surges and stutters. No misfires but the whole truck shakes pretty aggressively at speeds above 30 ish, almost feels like I have a large rock stuck in my tire if that makes sense. I drove it very gently to get a feel for it and make sure everything would work properly.

    Something interesting to note is my OBD reader is reading 33.7% alcohol in the gas, which it is not. It’s normal 10% 87. However the truck has been sitting since March with a full tank so it could be going bad. Also, my STFT B2 is -21.1, while all the others are normal.

    Any advice is welcome, i’m completely stumped. This is my first engine replacement and overhaul, but i’m confident in my timing work and I don’t think that’s the problem (I really hope at least)
