It sounds like you may have a vacuum leak. I would check for any vacuum leaks. Vacuum leaks will cause more problems when it is cold. Also check for exhaust leaks. Any louder than usual exhaust noise. The cold air hits the oxygen sensor in the exhaust system and drives the oxygen sensor crazy.
thanks...when starting engine idles hi and lo until engine warms
