02Sensors on 1997 Lincoln Town Car

The sensors on bank 1 and 2 are going out the check engine light came on and the shows they are running too lean.

I'll only add to ghostima96 that it could also be a Mass Air Flow sensor (MAF).

Please, do not just replace the two O2 won't help.

If both are running lean it can be caused by a vacuum leak or low fuel pressure
