    vaccum leak could be the problem. adjust your idle screw. and also check you fast idle control valve.

    When you touch the brake or clutch does it change any?

    If so you might want to check the brake master cylinder and booster. Might not sound like the prob but just check the cylinder for leaks. If it leaks replace it if its not the cylinder leaking change the booster.
    Trust me it has a lot to do with the vaccuum lines.

    Maybe, I had a jeep that that would shoot out of. Everytime I put it back in it seemed to run a little better until it shot out again. But thats on a jeep not a honda. BTW just to brush up that stands for positive crankcase vacuum, right?
