I have this exact same problem, so I would also very much like to hear what the Collective thinks about this issue. For me, it lasts maybe 5 minutes, or until the car is sufficiently warmed up. During this warm up period, if I try to raise the RPM to between 1000 and 2500 RPM, the engine loses power and hesitates until it gets to above 2500 RPM, then it runs smoothly. This entirely disappears once warmed up. I do not have the acceleration problems you mention in #4. Thanks, -Hank Eskin #1619 (5-speed)
