Klaus! How are you? Thanks for weighing in. 180+ on the sensors, incredible. We have logged mileage down a little over 3 in the city, and with gas still over $4.20 for regular here, and smog pending, I've decided I want to give this a shot. That said, today is the free day I have to get the smog done, and the sensor is not even on order yet, so I decided about two hours ago to just get the smog done without. Sensors certainly don't age without running, so at 80k, this one should be more than capable of producing good numbers on the meter. I'll post back with what I've learned. I am going to replace it though, and see if mileage improves. Everything else was done about 10k ago with virtually no improvement in mileage. Short of a clogged cat, which would show up in other ways, the sensor is about the only variable right now.
Regards,
Dave
