Oxygen Sensor

[David Vanden]

I will put in an oxygen sensor.  Thanks for the advice.  On a separate note
I just replaced the fuel pump and she is idling too high.  I tried
adjusting the mixture but that didn't fix it.  Any ideas?  Decreasing the
air on the throttle by setting the screw all the way to the right decreased
it but not enough.  Any suggestions?
