93 civic si brake prob need help

[driftuner240]

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

u drove it with the vac line off.

internal leak on the master cylinder would be my sight unseen guess.
