p1416 code My car just threw the code p1416.. which everywhere I look people say its the Air check valve.. well, I have the AIR removed and tuned out, and have for over a year.. what else could this be? The o2 sensor? I have headers, with o2 extensions. If that is the cause how do you check if its the sensor or the extension?
