OK here si my problem... At temeratures below 45F when first started, my car idles at only 1100rpm. Doesn't hessitate, doesn't shake or nothing like that, just idles low as if the engine was warm. Every once in a great while it would act normal: idle at around 1500rpm on start-up than go down as engine warms up. I know this is abnormal since it didn't use to do this the first 80k of its life. This is a '97 Altima with 145k mi. What could cause my car's low start-up idle in cold weather??
