It seems to have rough idle when I come to a stop at a red light. The codes the OBD 2 is giving me are P0113 and P0031.

Welcome to 2CarPros.

The P0031 indicates an issue with the heated oxygen sensor and the P0113 is with the intake air temp sensor. I suspect the O2 sensor may be setting due to the IAT. What needs done is to check both. I would start with the IAT, but the diagnostics require a live data scanner.

I will attach the diagnostics in the pics below. If it is something you can't do at home, please let me know.

Take care,
Joe
