I have had trouble for the past 3 1/2 months with my 88 325i conv. When I leave it overnight for several hours and then get into it to drive it hesitates within the first couople of hundred yards and seems like it wants to quit, but it picks back up and keeps on going. Doesn't do it the rest of the day. I've had the fuel injectors cleaned (twice!!!),the mechanic at BMW Huntsville, AL thought it was still the problem although I told him it had been done before to no avail. I've had the car in their hands three times now trying to reproduce the problem, but they say it isn't doing it for them. It does it almost daily for me, though!!!! Does anyone know what the problem might be????
