Hi Herbert:

Before you open the hood you may want to do some homework on OBD-II (On
Board Diagnostics).  All cars sold in the U.S. after the mid 90s have a
connector that's within reach of the driver (for your car I think it's
under the dash and you can touch it with your right hand).  The digital
data on this connector includes the miles traveled and I think info from
all the sensors in the engine compartment and most likely the injector
pulse width.  See <http://www.obdii.com>.  Some of the OBD-II data is
mandated by the EPA, but there is also manufacturer proprietary data
there, and there a lot of people that have hacked this and know what it
is. This is the connector the dealer hooks uses to determine why the
"Check Engine Light" is on.

Have Fun,

Brooke Clarke, N6GCE
