Just thought I would post a followup as I was able to get our 240 passed CAL SMOG today (whew!). Turned out the airmass sensor had gone bad..failed both tests in the Bentley. I put in a salvage spare and this one tested out of range, but not too far and the other one was just dead. I plugged it in and tuned it per the Bentley instructions for mixture. I also did the ICU/vacuum advance mod that was recommended, also filled up with premium. NOx dropped from over 2000ppm to 800 - 900 range and she passed...good for another year!

Thanks to all.

Cliff
