First, I changed out the Thermo Time Switch. Now the RPMs when the engine is warm it goes up to only 995 RPMs. I then had to adjust the dwell again.
Second, dummy me, thought the Idle Speed Thermistor was under the car on the driver's side. This is the cooling fan thermostat. So where is the Idle Speed Thermistor located. It is near the Y-Tube. Where is that? Any pictures or directions I can follow, I am having a mental block or something. Grrrrr. The way the car is idling now, not sure it needs to be replaced but would like to check it.
It is in the y-pipe and has a black two-pin Bosch plug going into it

Thermal Time Switch only affect engine starting. It provides the ground for the cold start valve. It would not affect idle RPM or dwell. If those changed, something else made those changes.
The idle speed thermistor is in the Y-pipe which is under the intake manifold. You really need to pull the manifold to get access to it. I would check if it works at the bulkhead connectors before going to the effort to get to the thermistor.
