    Adjusting idle

    My idle seems a little low on my 2003 wrx wagon. It is sitting around 500 rpm. I recieved a service manual on disk when I purchased the car. It really doesn't explain much on adjusting the idle? It mentions hooking it up to a computer? Is this the only way to adjust the idle speed?

    If idle were really at 500 rpm the needle on the tach would not move whether the motor is running or not. If the needle of the tach is on the first line below it's "OFF" point, then the idle is actually 750 rpm or so, and this is in fact OK. I strongly suspect your idle is 750 rpm.
    The world breaks everyone and afterward many are strong in the broken places. But those that will not break it kills. It kills the very good and the very gentle and the very brave impartially. If you are none of these you can be sure it will kill you too but there will be no special hurry. Ernest Hemingway, A Farewell to Arms, 1929
