[V8] Hot Start problems - but starts when floored

[Ed Kellock]

The ECU temp sensor is on the back of the passenger side head below the
distributor.

In some cases when it fails, it signals that the engine is too cold, causing
the ECU to throw too much fuel into the mix.  Hold the throttle wide open
adds air.

Ed - thanks for the reply. Maybe you could help me understand a little
better. Is that the G82 sensor that is near the top radiator hose?

Also, any thoughts as to why would it start (sometimes) when floored?
Thanks. -Dave
