'165 Minimum Air Question...

[Kevin Crain]

When you set min air, are you doing it with the IAC disconnected and then
resetting the computer before reconnecting it?  Sounds like maybe not...and
the IAC is at max open or damaged.

You set min air with IAC disconnected and fully extended, then zap the ECM
and reconnect it.  The 450rpm you dialed in with no IAC should turn back
into 600rpm or so when the IAC is re-enabled and the ECM takes over idle
speed duty.
