Re: V8Q: Reference Sensor & Idle switch BTDT

What codes specifically did you get?  If the ignition is turned on but the
engine is not started  then the ecu sets a crank sensor code since it has
no way of checking the part until the engine spins.  The code is cleared as
soon as the engine starts.  I would not replace that sensor without good
reason,  I have done these at the dealer and they are a PITA.  Submit the
codes and we can go from there.  As far as the idle switch goes piece of
cake,  If you are smart enough to test it reliably then its just common sense.
