Idle increases when brakes are pumped....
I have an 89 EF with a b18a in it, if I pump the brakes several times at idle, idle jumps ~300rpms. Anyone have any ideas on what could be causing this?

Totally normal. It's caused by the brake booster releasing air into the intake manifold. The EACV isn't fast enough to compensate for it. Same thing happens on my 'rex.
