Trouble Code : 1-2-1 700 1991

Map sensor checks out oK, took it apart pulled vacuum on it and voltage drops.
Connectors ok too..

I'm going to clean the throttle body too, as the idle seems to hunt
a bit and on a cold start idle jumps to 1500 rpm and slowly comes
down to 1000 then drops to 750, and while driven stumbles down to around
500 at times...car shudders..

This is fun! The beast has run just fine up until this winter...
