Bouncing idle while pumping brakes?

anyone else have this issue? while in N if i pump my brakes fast, my idle bounces between 1700 and 800. i also have bouncy idle just in neutral sometimes as well but its only -+100 RPM's or so. im thinking it might be my TPS. i have not checked it yet nor have i looked for vacuum leaks. my car missfires every 10 seconds or so too at any RPM's. ive cleaned all the valves and tightened the fast idle screw and reset my base idle. any help would be greatly appreciated.

Pumping the brake "creates" a vacuum leak which cause's the increase in idle.
(Vacuum booster) - It's normal.

As for your other issues - when was the last time you changed the plugs/fuel filter?
