It's a 4x2. Thanks for the link and EPA rating info! Do you think tapping into the sensor is better than the ECU test (mode II) that you do at idle? I think it just lets you count the lean-rich-lean-rich flips in a certain time window...

I'd almost think that the super-sensitive OBDII ECU would catch sluggish O2 sensors, but something's definately not right - so I'm ready to start diagnosing... especially since gas prices just took another 7 cent jump today!

P.S. Did you say 30MPG in the Caddy?? With a 4.6L V8?? That's amazing... does it turn off one bank of the engine at cruise or something? Best I've done on the Q is about 22. That's cruising at about 80 MPH 400 miles straight - basically pump to pump.
