error codes!

Hey guys how's it goin? Last time I was on here I mentioned I was doing a B18 swap in my EF! Well now its all done and im driving it daily!! I put in a B18B1 running on obd0. I noticed a few error codes that the computer threw out they were Code 10-Intake air temperature and Code 43-Fuel supply system.

I've tried doing some research and code 43 can be either 02 sensor, vacuum leaks, or even a bad ecu? I'm running a PR4.

Code 10 seem's to be just a bad iat sensor?

Would love some input from you guys!! Thanks in advance!

Edit: BTW The car runs and drives fine no idling problems or lack of power.
