On my 82 Coupe CIS it has always cranked for 6-8 seconds when cold before
starting.  Then it idles a little rough.  Once warmed up it cranks for 1
second then runs well.

I'm in FL and it has gotten colder then normal(down in mid 30's).  Anyway, if
I go out on a 35F morning and start it, it fires the instant I hit the
ignition switch.  Then it has the most beautiful idle, and runs purrfect.
But, if it was a 45 or above morning, thats when it crank 6-8 seconds before
firing.  Thoughts?

I unplugged the CTS and will see if it has any effect, there was some mention
in archives.

What is the female plug for right by the oxy sensor wiring.  Part # 171 971

I get 8.2 volts across terminals when running...what does this mean?
