    2003 9-3 conv running poorly w/ odd symptoms

    I hope I can explain this well and If there's already a thread I apologize. my 2003 9-3 conv was running fine and then suddenly lost power intermittently, then went from running OK but rough for a few seconds to could barely keep it idling by feathering the gas with the following odd symptoms:

    while barely running:
    1. boost Gauge was all the way into the red.
    2. check engine light is blinking.
    3. wife said black smoke from tail pipe.
    while running OK but rough:

    1. boost Gauge normal.
    2. check engine light on, but not blinking.
    3. no black smoke.
    the symptoms change instantly, on, off, on

    I haven't done anything yet, could it be blocked exhaust, some loose baffle?

    where would you start looking?

    Any help would be very much appreciated!!

    John ( less his Saab)
