Yes, the post cat is the downstream 02 sensor. I am going the plug defouler route since my air fuel ratios are solid. I picked a kit up this evening.

I'm using my OBD 2 bluetooth adapter, Torque Pro app on my android phone. Among many other sensors monitored are both commanded AFR and measured AFR. I am in Niagara Falls now but when I return home in a couple of days, I could send you a pic if interested.
