Hi Grif,

Sorry, but my memory slipped regarding use of Dwell Meter on LH 2.2 AMM. It just doesn't work! The Bentley manual is wrong! You have to use an LED, or meter the O2 sensor.

I learned this last month when doing the adjustment on my daughter's car. The details (from Art Benstein, David Hunter and Jim McDonald) are in this thread>>

Basically you have to use an LED on the test point (and trust your eyball calibration) — OR use a meter on the O2 sensor and adjust to the lowest AMM setting that gives the correct voltage swings.

I wanted to point you to a follow-up thread, but don't want to waste anymore time looking ("My Posts" doesn't seem to work for prior months???), so am posting this now.

Hope this isn't too late to be of help
