Hi just quick question, .
My car idles at about 1000 rpm when it's just turned on. I.e. when the engine is cold. Then as it warms up I notice the revs go down abit and stay there to about 750 ( cant remember exactly). And then one time it was freezing outside and i noticed it start to idle abit more than 1000.
Is that controlled on purpose to help warm up the engine or is it a sign of engine problem?
