The pressure readings are the same... I am disappointed. I swapped it back in, and there was really not much change.

My new (failed) emission readings are:

HC: 0.97
CO: 12.79
NOx: 1.36

Argh. Going to hunt around for vacuum leaks, maybe yank the throttle body off and clean it as well as what I can reach of the intake manifold.

The cat was replaced May 2003, so unless it went bad in about a year, I don't see that as being the cause.

Also, no OBD codes are present other than the chronic 3-2-1 cold start valve that doesn't mean anything.
