I'm sorry that your car failed.That was the problem that I had with my 1997 Ford Explorer.The 02 sensors.My husband hooked up a code reader device and he erased the codes.And then the check engine light went out.I had to drive it to get a certain milage on it.And we took it back to get it inspected again and it passed.I hope that you get your car to pass.Good luck to you.
