My '65 230sl is demonstrating some unusual habits lately: when driving off, the engine seems hesitant to rev and proper acceleration only occurs once the vehicle is moving. The engine otherwise is running smooth and the autotran is not giving any problems either. Engine temperature doesn't seem to make any difference and the symptom appears to be the same in all drive selections (2,3 and 4).
I am asking for advice because I don't know where to start looking; is the auto gearbox to blame or should the engine be tuned? The car only has 17K documented miles so wear seems to be out of the question.
Thanks,
