hey my 1995 honda prelude (h23) recently has had an idle problem. when it is in park (A/T) the idle will surge to 1500 then drop to around 800 and do this until it goes into a gear. also, when applying the brakes in park the idle will drop around 600 and the car will almost stall. the pedal feels mushy, brake lines have been bled and fluid is fine. i think the two problems are related somehow seeing as how the idle drops VERY low when the brakes are pressed.

the idle problem sounds like a TPS problem to me, but i have no clue about the second problem. maybe a master cylinder? opinions needed, this crap's annoying and this is my daily driver
