When at idle - take a look at your AFR and trim numbers for Bank1 and Bank2 - the AFR and Trim numbers from both banks should be very close to each other. IF however, the AFR number on Bank1 says 14.7 and Bank2 is noticeably lower - check the trim numbers for both banks. They too should be very close to each other. If not, you might want to take the car into the dealership and raise the concern of a leaking fuel injector.
