Didn't want to make a new thread so.... My idle seem fine after the car warm up and start warms..... but during a cold start up the RPM will drop down to 100 and even stall sometime???? Any way to fix this problem? Is something missing??

Coolant temperature sensor. Replace it.

It's the 2 wire sensor on the coolant neck near the dizzy.
