OT: QUICK! Digifant 2 HELP!

[scirocco at vintagewatercooleds.com (Eric S)]

Anyone good with Digi2?  I need some QUICK help, my temp registration
expires today, and I HAVE to get this thing to pass emissions.

Last week it failed for too much HC (unburned fuel).

It has, a terrible idle, and it misses at different parts of the rpm band.
 I have replaced: cap, rotor, wires and plugs.  Set the timing (properly
for Digi2 which is a wierd process), and it still was acting the same. 
So, just out of curiosity I pulled the plug to the coolant temp
sensor...and guess what?  Runs fine.  Without a coolant temp sensor, what
does digi2 default to?  A lean mix or a rich mix?  I suspect that my
coolant temp sensor is bad and was telling the digi the engine was cold
constantly, richening the mixture to a point of making it run like
garbage.  But I don't know enough about digi2 to say for sure.

Anyone, please help, I HAVE to pass emissions in the next couple of hours
before I head to work and get plates today...I'm just praying that with
the coolant temp disconnected it will....
