My Prius wouldn't go at a stop light. It was in drive. When I hit the accelerator the engine would rev but the car would hardly move. It finally got moving after a few seconds, then did it again at the next light. Then it was fine.
There is a TSB for reduced power when accelerating from a stop TSB (NiMH only): Reduced power when accelerating from a stop | PriusChat
Overlooking that the title doesn't really match the question he asked.......... And the car listed in his profile is not the one he is apparently asking about......... It is rather strange that this went 3 weeks with NO responses. EDIT: Never mind. He hasn't been back to check for answers in 3 weeks either.
