    This morning I had a a P0108 error code (Manifold Absolute Pressure/
    Barometric Pressure Circuit High Input) come on after I lost control
    of my 2000 Legacy GT 5speed on the highway - fishtailed about 4 times
    and then did a complete 360 before coming to a stop (deer jumped about
    a quarter second in front of me at 65 mph). Now the car has a really
    rough, low RPM idle but is fine at speed. Does anyone know what the
    cause of this could be?

    Look for a vacuum line that may have come off. Intake, throttle body
    would be a good starting point.

  4. Good suggestion. I would also just clear the code and see if it returns.
    I suspect it will, the rough idle seems to point to a real issue, but
    sometimes clearing the ECU will work miracles.

    It might. Subaru ECUs are adaptive. If it sees a code, it assumes
    something is wrong and tries to compensate for it. I have cleared misfire
    codes (from my wife leaving the gas cap off) and the car smooths out.

    Just wondering what caused your wife to misfire and what kind of gas cap
    she has... i might one day need one for mine... ;)

    Wives misfire constantly. Since only their creator can understand them and
    they seem to communicate by telepathy or something, I doubt anyone will ever
    figure out why they misfire. And when they do, the response is certainly a
    code of some kind; and they don't need any kind of cap to do it...

    Sure wish I knew how to clear those codes. Mine misfires all the
    My Subaru runs fine though.

    A lot of times you can clear the codes by disconnecting the negative
    battery cable for a couple of minutes. Of course, it will also clear
    your settings on the radio.

    $70 at your local walmart and you'll have a code scanner that'll clear
    and read them. I bought the nicer one at $100 and it's come in a lot
    more handy than I'd ever think.

    Or you can take the car to auto zone when they're not busy. They'll
    scan and read the codes... but i dunno if they'll erase em though.

    Chocolate and roses. My Scoobie runs fine too.

  12. Won't clear a 2000 Sub. Codes are in NVRAM.
