I've got a bit of an idle problem with my 97 Civic - D16Y7 1.6L

It seems the idle drops when I depress the brakes while the car is in gear
(automatic)
I would say, that when in Park, the idle sits around 500 Rpm. It use to be
600 or 700.

It even drops when raising the power windows and you reach the top. ie; when
window reaches the top, and you keep your finger on the switch, the idle
will drop about 100-200 Rpm then settle back to original.

I've just changed Cap, Rotor, Wires and Plugs. Nothing really changed.
