Y'all,

    My 1.9L idle started to run high & erratic 1000-2000 rpm.  I checked for
vacuum leaks, found none.  Did the check for the aux air valve and volia -
according to Bently that was it.  I tried to clean it with no luck so bought
a new one.  Just installed it and the same thing is occurring.   I did clamp
the hose from the aux valve to the throttle body while waiting for the valve
and it ran great , even cold. ( 23.5 mpg combined (USG)) .   So I re-clamped
the hose closed and await your wisdom.( the harness is giving 13.5 v to the
aux air valve with engine running)  Whats the chance of a bum new valve?
