crankwalk is when you ride the clutch, always with the clutch enguaged, etc. The crank begins to walk in the mains. You have to get it fixed by pulling it and getting to news/bearing, if its too bad, then you need a new motor.
4g63 (the turboed cars and spyders have it) are NOT as likely to get it as the rs/gs chrysler 420a. To tell if it has it, simply drive it and when you engauge the clutch, if you feel a vibration, its most likely crankwalk.
Neutral safey switch allows the car to only be started in neutral and not in gear. If its gear, then someone can push start your shit while its there.
