Cold weather starting vibration
My 04 6MT coupe has done great this winter, and never failed to start in down to - 25 F weather. However one thing does worry me : at any temp below 0, the car shakes upon starting. When the clutch is released in neutral, the RPM drops by about 500 and the shaking changes in frequency and intensity. This continues for a minute or two before the car warms up and everything's fine which I take as a sign to start driving.
It feels like the clutch is slightly dragging on a rough flywheel... Has anyone else experienced this and did it ever cause problems down the road?
