my car also does it when cold first thing in the morning. i think it has somthing to do with the cold idle setting in the computer, if you drive off before 6he idle settles down, then its a bit sluggish and hesitates between gears. i take it yours is an auto? mine doesnt like re-application of throttle after changing gears. If i thrash it, i can make it clear its throat, and its good as new.
