cold start rough idle only in gear
My 7 suffers from an erratic idle when in gear after a cold start.It idles fine in park after a cold start but when droppped into either drive or reverse(auto tranny) the idle will bounce a few hundred rpm in gear until the engine warms up(usually two minutes)and than it is fine.Also,if I let the car warm up in park that does not help for when the car is put into gear it will still idle a bit rough and will do the same thing when the car comes to a complete stop such as at a traffic light or a stop sign.Again in this circumstance the idle will jump on occasion but stops after the engine warms up as the car is actually driven.Could someone please clue me into my dilemma.Thanks.
