I have a code of PO113, bank 1 and my car misfires like when I drive the the car with the air conditioner on? Does the pump have a filter in it? Do I need a new pump? Jim

P0113 is for the Intake Air Temp Sensor circuit reading incorrectly. I am attaching Prodemand's step by step instructions on how to fix it. Please look into this and let us know what you find.
