I have no idea what you're saying.
If it revs that high at idle you might have left a sizeable hole for air to get into the intake after the throttle body. The rest: pictures mof what was replaced might help?

That last error is putting you into limp mode, it sounds like. But with so many errors that's obviously not the only issue or maybe not an issue at all. MAF circuit errors are also not great, the var has no idea how much air it's getting.

Possible other wires are also not connected, or the harness is damaged? Why was the motor replaced in the first place?

When I got the car it had no compression in the back roader so took it a part and it completely trashed the house in the roader so just ordered one from jdm so would you start with the maF and just go from there ?
I looked about 12 different times to make sure everything was plugged in

I guess step 1 is clear the codes and see if they come back. Then make sure the battery, battery terminals, and grounds are good, healthy, snug and clean.

After that I would start looking for damage to the wiring harness. Possible to pinch it while putting the engine in.

For the OMP in particular, it's easy to put it in incorrectly which could cause limp mode. There are posts here you can search for about how to align ot properly.

I'm not really sure you can reprogram the OMP out entirely. Just plug it in, and add a 2-stroke feed if you don't want to burn engine oil. It is actually useful

No. Only OMP or coolant temp sensor.

Yep so you need to review the OMP installation and wiring connection
