Second code was probably P0171 System too lean, P1131 is O2 sensor lack of switching due to over lean condition.

Clean the MAF first, then check for leaks between MAF and TB. And check that the oil dipstick is seated properly.

Edit. It might not be the IAC valve. But if you want to change it, this is the location and instructions.
