And an apology

For a Pavlovian response to a CIS question about a different issue than one I am working on which isn't going to be helpfur for Mac and his problem.

Plus after reviewing things, I find I had the wrong idea in my head. On a hot (35*C) engine, the FV/O2 system DOES operate to adjust the idle AFR, just as it does for cruise. Which would be why the manuals say disconnect the O2 sensor when setting the idle AFR.

Mea culpa.
