When I first start my car from cold it idles at 950rpm as it warms up the idle slowly increases to about 1200rpm when up to standard temp it never drops below 1200 rpm. WHY? Where should I start looking. Is my idle speed box of tricks behind the drivers seat playing up? and how do I test it. It seems to make no difference if its plugged in or not.
