    This has happened about a year ago and then again this morning.
    It starts as if the battery is just about dead. Once it starts it idles
    really rough with a white smoky exhaust.
    When I turn it off and then restart it -- it acts as if nothing ever
    happened. It runs and idles just fine.
    Can someone explain a possible reason for this. The warranty is about to
    expire, should I be concerned.
    The tank showed about 1/4 full this morning when this happened. When I
    search the group the only thing I came up with that was close to this
    problem was caused by a near empty tank.

    Thanks for any assistance.

    Water in engine!

    Reason: White smoke/misfire.
    Water does not compress so can cause symptoms like a flat battery.
    Water does not burn so causes a misfire.
    Small amounts can be burnt with fuel but causes white smoke.

    Causes...Been wading/off road? OR condensation build up in
    petrol tank. Bum load of fuel

    Maybe a tank drain is in order.


    PS Doubt it will be the Head gaskets due to timescale since last occurrence.

    My 2003 Forester did the same thing for a while. It turned out to
    be the oxygen sensor.

    I have the same problem.
    I am guessing that when I was hit and had a new rear quarter panel
    replaced, the welding created some kind of short.
    just a guess.

  5. Yes, same here - '04 Baja.

    I noticed a similar problem with my 04 Baja. Hard to start (cranked
    okay), ran *REALLY* rough, and lots of smoke. Turn off and try again
    and all is well. This *only* happened when it was cold - the first
    start of the day.

    I also had a slight TC with it - rear ended a pickup truck - *ZERO*
    damage to the Baja, but folded the bumper of the truck under the truck
    bed. This happened about 10 feet away from a cop. He came over asked
    if anyone was hurt, and told us to sort it out ourselves. Anyway, I
    don't know if the fault developed before or after this incident.

    I took it to the dealer after I got tired of it. They tried to
    re-create it but to no avail. I lived with it for a while longer.
    Again I took it in. They evenutally got a note from Japan saying that
    it was due to pressing the gas pedal *before* starting the car. (A
    carry over from the old VW days I'm afraid). I thought that that was
    a bit odd. but from then on I did not hit the gas and I never had the
    problem. They said it was a software issue. Hmmm.

    I've since gotten a Turbo Forrester, and have not noticed the problem
    at all.

    Good luck.

    None of the cars I've owned that were MY89 or newer required that gas
    pedal business: all of them just required a fully depressed clutch
    and a turn of the ignition key to start the engine. Old habits do die
    hard, don't they?

  7. Yes, they do. Just showing my age I guess.
