id still like to know what your o2 and co2 numbers are, as well as co. it can help narrow down the cat. did you ever call on getting the cat tested?
This was before I got my new O2 sensor. This test was also taken with a huge exhaust leak.

CO2 @ 15 MPH = 9.1CO2 @ 25 MPH = 10.3O2 @ 15 MPH = 8.3O2 @ 25 MPH = 6.6HC @ 15 MPH = 50, max allowed is 88, passed.HC @ 25 MPH = 21, max allowed is 53, passed.CO @ 15 MPH = 0.00, max allowed is 0.52, passed.CO @ 25 MPH = 0.00, max allowed is 0.50, passed.NOX @ 15 MPH = 1394, max allowed is 704. FAILEDNOX @ 25 MPH = 1261, max allowed is 738. FAILED

Keep in mind this was when my vacuum lines were routed wrong, my egr was not working, and i had an exhaust leak.
