1991 22-RE mystery

afternoon all,
this is my first post, and im sad to say it's asking for advise, I really like the community here and have been a toyota man (22-re woot!) for a few years.
I'm having a problem with my 4runner that Im just a bit lost on, hopefully someone there can lend a helping hand.

After my 4runner warms up it has trouble idling properly. It will idle at about 1500 RPM and then will fluxulate between 900 and 1500 whenever i have my foot on the brake. when my foot is not on the brake it will idle at 1500. also if the air conditioner is running full blast, the idle will not fluxuate.

im hyper confuse, but have a bunch of vacume tubes and split-T's.
any ideas?

The answer is simple, it's fluctuating because the idle is set too high. It should be closer to 800, not 1500. Get the idle in spec and the fluctuations should go away.
