    when i'm crusing down the street in neutral it idles correct (800-900)
    when stoped at a light it idles very low (200-400)
    when i press and release the brakes very hard it idles up for a second, then back down to (200-400) (it idles up after i let off the brake)
    when i turn the air on it idles somewhere in the middle (600-700)
    when i tap the gas quickly while idling: it almost stalls sometimes, but if i get on it slow in revs up just fine

    my best guesses for cause of problem:
    fuel problem: filter/injectors
    vaccum leak: ???

    any suggestions?

    no vac leak would cause it to idle really high...

    did you adjust the idle screw?
    did you try the IACV test??
