Help, please. I recently bought a 1995 850 GLT with A/T. It has about 67,000 miles. When the car is cold, e.g. has sat all night, then most, but not all the time in the morning, for the first 10 minutes or so, it will buck several times while I am at low speed, and sometimes will also apparently shift in several gears with no logic. The tach will go from about 1700 rpm to about 3500 rpm, and back to about 1700 rpm, and then to about 2200 rpm, etc. It refuses to do it at the dealership, and they report that the diagnostics show no codes. I have left it overnight there, and they and I have both driven it first thing in the morning from the dealership, with no problem. (figures, doesn't it?) I live at the bottom of a hill, which is the only difference I can think of between my initial 10 minutes of driving and the dealership. I hope someone out there knows what's up with this car, because it is driving me nuts. (no pun intended?)Thanks, Richard.
