Was looking up this info and struck gold. Really appreciate Rennlist. One thing I seen that didn’t seem right was the acronym for AFM, I believe it’s “air flow meter” not “air fuel meter”. But who knows with the Mendela Effect these days.

Nicely done, but isn't there one more line that goes to the fresh air flaps on the blower/heater assembly?
I have a leak somewhere in this portion of the system ahead of the heater control solenoid, need to sit down and find it....

On the factory manuals, I see where that fresh air flap has a vacuum hose under the plastic by the firewall (in front of fresh air blower). I could see the hoses under the edge of the plastic. Not sure how to take the plastic off so you can trace where that vacuum hose ties into the rest of them? Not sure if that hose goes to the heater/ac "box" under the dash, but it must, since that is where the flap controls are.
