i don't have the temperature sensor hooked up. the one on top of the engine. and the CSI wasn't working before due to a bad ground on it.
I'm confused. The temp sensor on the top of the engine IS the ground for the CSI. When the air temp is below freezing, it closes and the one terminal is shorted to the case and this provides the ground to make the CSI work.

i still don't understand the AAR then cause it is open when i start the car but doesn't make the car rev high to 'warm' it up but it does open and then close fine maybe 5 minutes after the car starts. is the car not supposed to idle high at first when its this hot outside and only when its cold outside?
The AAR just provides a little extra air to the intake when the AAR is cold and thus the engine is cold. This helps the engine run smoothly when it is just started and is cold. If the car is hot and turned off, the AAR will share some of the engine heat and when re-started, the AAR may already be closed.
The CSI is just for temps below freezing and the AAR is for all temperatures when the engine is cold (ie., room temperature).
