RE: V8Q: Reference Sensor & Idle switch BTDT

["Buchholz, Steven" <Steven.Buchholz@kla-tencor.com>]

Thanks for the thoughts ... BTW, I read the codes while the engine was
running ... 2112 & 2121 ... which I decoded from the V8 service documents as
the reference sensor and the idle switch ...

The reference sensor is a common cause for hot starting problems on the V8
... a problem my car has ... and I confirmed the idle switch fault with an
ohmmeter on the pins ...
