Connecting 'vacuum amplifier' causes hesitation off idle

You can imagine the sad day in the engineering dept., the day those boys were told to design the air injection system.

It was bad enough saddling the poor old slanty with super low compression, and power robbing systems, but then they added insult to injury by having to ram fresh air into the manifold, to complete the burn, which shoulda happened in the chambers.
You gotta wonder about the people behind the mandates. Of the people/for the people ....hah.
The good thing is those days are behind us now, and they led to new and better engines, with higher compression again, better year-round driveability,more mpgs, and most importantly MORE power! Or at least more power per cubic inch.
