Thanks for the info...especially not to use cruise control and stay at the lower end of the range...will try.

The O2 monitor and EVAP monitor are not ready. SMOG shop said they can let EVAP slide but O2 is needed.

I also suspect something is preventing the O2 monitor to set. I asked four different shops (including one dealership) and they all said nothing they can do when there's no check engine light.
