"between temperature" stumbling/hesitation

[james accordino]

Not sure about NA engines, but isn't there a pressure
regulation control during this period?  Warm up
regulator?  I'd check this device or it's control (if
any) circuits.  For the harnesses, I made my own.
Sleeved alligator clips are available all over and the
connecters can be gotten at a wrecker.  Nissan used
the same connectors for more than a decade.  Amp?
Many different configurations can be made very quickly
and easily if you can get some connectors with 6-12"
of wire.
