When it's cold and i first start it, it idles at between 1100 and 1200. But once it's warm it idles right at 900 or maybe a tinge more. When it's really warm though it idles at 1100 or 1200 like when it's cold. Whatsup with that????

 

Don't know, but you do know that your tach shows 200-300 too high (typically).

 

Also, keep in mind that the engine does compensate for a/c. I wouldn't be extremely worried about it if your car is running fine. If you REAAAAALLLY think there is a problem, get your car scanned.

 

The car is running perfect. I don't have A/C any more. And I have an Autometer tach, the stocker is way off.
