What about tring to reset the computer and see if it then comes back. When I rotated the MAF it came on but one reset it hasn't since.

The O2 sensors have no idea that the cats are gone - the cats are downstream of the sensors. Did you damage the rear sensor or forget to reconnect the cable? Rather than guess, please check the codes. It may be something non-related to the O2 sensors.
