I recently just got a check engine light come on and had it scanned. It gave a code P1415. I had the air pump and air check valves replaced about 4 months ago. It's running rough and my gas mileage is worst. Please help

that should be for the passenger side check valve i think. I would check the plug and make sure your wiring looks ok.
