So it dropped down into the high 30's this morning and I discovered that the CRX won't stay idling upon start up. It fires right up, and then dies. I finally cured the problem by starting it up and giving it some gas right away and held it at 2k rpms till it warmed up a little and then it idled fine.

This never happened in warmer weather, and I'm new to CRXs and to Cold weather... is this something that's normal? How can I fix it if it's not? Thanks!

 

I would check your fast idle control solenoid valve, located on the back right of the manifold, it is used to give the engine more air when it's really cold.

After that, I would just look at your base idle.
