Fuel Mixture? was Cold Start Problem- Last Chapter(I Hope)



Seems that fuel mixture was the cause of  (or last remaining cause of) my 
cold start / warm up problem. Started the car this morning (86 4KCSQ). First 
a short stumble, then a surge to 1400 RPM and immediately settling at 1200 
RPM. Soon thereafter dropped to a smooth 1000 RPM. I would probably attribute 
the stumble to a lack of CSV assistance. That is my next shot, although I am 
really happy that I have gotten to this point. Bentley mentions everything 
but fuel mixture when troubleshooting this type of problem. Leaky CSV / Leaky 
Injector / Improper Idle setting / pressure plate not moving freely / warm up 
enrichment function not functioning properly are among the items they suggest 
to look at.

Have been checking CSV which does not seem to be doing anything. I suspect 
the Thermo Time Switch. Is there anything I need to watch out for when 
removing the TTS from the back of the head on my I5. Fluid loss or anything 
like that? Usually TTS goes in a coolant line - right?

Thanks to everyone for the 2 months of assistance on this bitch of a problem.
