Hi folks. This is about a 1984 B23F, LH2.0, automatic transmission.

I'm trying to check my AMM as a possible reason for failing emissions (HC is over 800, 4X that allowed). I've carefully recorded errors in Bentley that have been posted on our forum over the years, and one concerns pg 241-27, in which (if I've got this right) we're instructed to cross-out "LH-2.0" in the heading of column 2 that reads, "To check/adjust idle mixture (using dwell meter or LED test light, LH-2.0, LH-2.2 only)"

Does that mean that I can't use a dwell meter on the pink wire to adjust the pot on my AMM? Or does it mean that I can't use the LED test light, but I can still use a dwell meter? I've kept the AMM with an adjustment of 300 ohms measured across the pins in the socket, but I'm thinking that maybe that isn't right, and a better adjustment should be done.

But when I take out my old dwell meter (which I haven't used since the early 1970's, when my cars had points in the distributor), it's not showing any dwell reading at the pink wire! And I don't know any other way to test the meter -- maybe its broken, or maybe there's no signal to measure in an LH-2.0, as possibly implied by the correction for that page of Bentley. Or maybe my AMM or O2 sensor is dead?

So anyone know the answer?
Thanks, in advance.
