Will a bad 02 sensor throw a cel? Im having a hesitation problem, but when i use the ac fan, which blows air into the intake, it makes the car run normal. This has to mean my air/fuel ratio is off. Would this be a case of a bad o2 sensor? If not, what could it be?

Yes, bad 02 sensor throws a cell. And yeah a bad o2 can cause a hesitation problem. When they go bad they just start giving funky readings that make no sense at all.
