  A friend of mine recently picked up a 85 rocco 8v.  Since then, we've =
been doing all the usual things the PO's never do, spark plugs, wires, =
vaccume hoses, oil change, new grounds, engine bay cleaning, new =
altenator, etc...

  So now we get the beast running, and I wanted to work on the idle a =
bit so I wait for the fan to come on and go off, adjust the idle screw =
and get her down to about 950.  Figured I'd let her sit there for a bit =
and after the fan has come on/off about 3-4 times, the idle all the =
sudden startes hunting all over the place.  She climbs as high as 2k, =
drops to 1k a few times and then will settle at 1800.  So, heres my =
question, WTF is up with that.  My 16v likes to idle hunt a bit right =
after start but then goes to about 950 and stays put.  This car wait =
till she's good and warm and then plays hell.  My thoughts are O2 sensor =
or even wrose, the ECU.  What is the general thoughts of the great and =
knowledgable list?
