off.

advertised, but not for my model.  Does anyone know the source of this
rebuilding.

trust the values in the Cardisc enough to drop $500!).  All you need to do
is measure the resistance between pins 1 and 4 on the airflow sensor(there
are only for pins so this makes it easy) after disconnecting the connector.
This only takes about 15 seconds of time under the hood.  Also, please note
the outside air-temperature.  Thanks for your assistance in advance.
