i have a 1997 ford crown victoria with 160,000 miles on it i recently went to the emissions station here in chicago they pluged in their scanner and the car was failed because the catalytic converter box read NOT READY. why is that and how can i remedy the problem. thanks, Kyle.

You must have recently disconnected the battery or cleared the computer. The computer needs to be driven during every possible scenario so it has a chance to test every system. This can take a couple hundred miles of varied type driving.
