AFM problem
I thought I'd offer a follow up on my issues listed above for anyone in the future who may read...
Most everything is square now and here are some results:
For the random engine cut out issue, it turns out the AFM was causing my problems. Under the black plastic cover on top of the AFM is a rheostat looking arm that was loosing connection sometimes which would then cut fuel resulting in my engine dieing. The arm tension was retightened and I have not had anymore issues.
For the random heat/cool A/C, I swapped the amplifier out for a new one and all is well. I did have to recharge the system, and I am cool now, even in near 100 degree F weather.
I have taken care of a number of other items in the name of preventative maintenance - tightened timing chains, replaced hoses, new fan and fan clutch, fixed exhaust leak, installed tappet hold down kit, etc. and have been driving daily to and from work (~30 miles one way). So far so good.
What is everyone averaging in mpg? Just curious. I'm pretty consistant with 15-16mpg average (60-70% highway driving).
Thanks,
Eric

That was exactly the problem on my '86 V12:
When returning to idle, the engine would turn at approx. 450rpm and then slowly die. Checked out the vacuum system and found that the kick-down hose on the tranny had come loose. Fixed that and she idles beautifully now.

You are quite welcome. some has been fun and some quite the other way.
The DOHC and BW 66 are gone. In their place is an LT1 SBC and 4l60E transmission.
Not voluntary, but, quite satisfying. I liked it as it was and enjoy it as it is.
I term it English elegance with an Italian flair and reliable American power.
I particularly enjoy the OD. 70 MPH or so at about 1750 RPM. Yet plenty of urge on adding more pedal...
