during initial warm-up sequance in the AM…but the symptoms will
disappear after engines warms up to normal operating temp…any
ideas suggestions to look for…?–

Lead,
My 85 had similar complaints , and I contributed it to the AAV,
which as you can see has its main draw into the rear of the B bank
inlet manifold, then via the balance pipe to the A manifold. And
since it goes away when warmed up, the AAV is closed, so the vacuum
draw is minimal for acceptable hot idle only. Mine was cured when I
removed the AAV and replaced with 2 electric solenoids, switched on
for cold start, and drawing equally to each manifold. Grant–
