does not move. Any idea? I have a 1999 ML320 (125000 MILES). On occasions while driving it stalls and pressing gas does not move the car . To clear that I either turn the car off and on again or shift to neutral and back to the drive. Then the car drives normally. This happens once every three weeks. Any idea what causes this?. By the way I also sometimes get check engine light which gives transmission code and it clears itself. But when car stalls there is no indication. Any help will be appreciated.
