My SES light have been on for a while and I took my car to autozone to get the codes read. Below are the ones I found:

P1320 - Ignition Signal. Do I need to replace all of the ignition coils?
P0174 - Fuel Injection System Too Lean (Bank 2). Bad Injector????
P0505 (Twice) - Idle Air Control Valve / Auxiliary Air Control Valve. I just cleaned my TB, could this have done something to the IACV? I also re-installed my OEM intake.

Any help would be greatly appreciated!
