Obd2 codes. Help please

Just replaced thermostat and coolant temperature sensor and my check engine light went off.
Driving today and it popped back up with these codes... P0171, P0113, P0123.
Said something about system too lean and high throttle input sensitivity.
08x 42k , I fill up on 93 and have a straight pipe and k&n.... please let me know what to look for. THANKS

They could all be related the the tasks you just did.

Check the connectors at the intake air temp sensor, and the throttle position sensor, and coolant temp sensor. Look for them to have bent or corroded pins, and properly seated.

If it's not those simple things. I'll post the data for the codes and the list of things to look for.
