Yes, a ported TB can cause a high idle if it wasn't done right and the IAC is bottomed out.

You need a scanner with data stream to see what's going on.

The car threw a P0131 P0137 and P0171 codes. Is there anyway to differentiate if the codes are for a front or rear oxygen sensor?

Those are all lean codes. Check for vacuum leaks.

Are you asking if those codes are saying which sensor locations they are?

Yeah, I was trying to figure out if one of them was saying the front O2 sensor is going out.

bank 1 is driver side
bank 2 is pass side
sensors 1 are front
sensors 2 are rear

Do a google search for the codes. What I wrote above will help identify which sensors the codes are talking about. That should help
