    i got a 93 civic si hatchback with a d16z6 5 speed tranny p28 ecu eveything is stock. my prob is i bleed my brakes like 50 times i got a good stiff pedal before i start the car. when i start the car i got no pedal and everytime i push down the idle changes but goes back down as soon as i let off. so i bleed the lines with the car running and it did nothing. with the car running i disconnected the vacuum hose off the brake booster to the manifold and the pedal stayed stiff and rpms didnt change but, when i drove it the pedal was stiff but did not stop. need a litlle help lmk

    how about a vacuum leak? they can cause irregularities in idle when using the breaks.

    the check valve in the vaccume line to the brake booster may be faulty, you should chack that it only takes 2 sec

    Bad booster! They do go bad.. especially if it may have been owned by a woman.
    Also, check back under the carpet, where it comes through the firewall for leaking that won't show up until you get a soggy carpet stain.

    I've had that on several cars that I kept bleeding and bleeding but it would loose after a week or so.
    Then found the leak up by the peddles.
