My car was idling perfectly when it was 100 degrees outside. Now that the weather has dropped quite a bit, my idle is high and takes a while to calm down. Should I do a base idle reset?

It's taking longer to get to normal operating temperature, so the idle is supposed to be higher while it warms up.

Great question..... I'm not sure actually. I haven't swapped it out since getting the car a few months ago. What temp thermostat do most guys run? Car still runs fine, I just feel the idle is a bit higher since the temp outside has dropped quite a bit. It's not the high idle when car is cold still. Idle just seems to have bumped a couple hundred RPMs.

Factory t-stat is 192, many change to 180. Do not use a 160, factory computer will not enter closed loop.
