Agree with Chowdah. My 1st impression is that you didnt connect the sensors COMPLETELY. You really have to push in hard on the plug in to ensure a good connection. The fault was probably pre-cat heater control. It wouldnt cause your car to run any differently.

1. Unplug, then re-plug all the connections back together with the above in mind.
2. Invest in a Peake code reader....Not a code reader from Autozone, or similiar. PEAKE reader. They are exclusive to these vehicles and priceless.

Good Luck
