emergency - i was just on my way to the gym approx 930pm (pacific standard time) and the check engine light came on , then the car had no power as if a spark plug was loose . i popped the hood and pushed on the plugs , but nothing else happened and no change. it's like the car is stuttering with no power, could this be the head gasket or would my car not be driveable at all if it was . if it isn't that what could it possibily be? i don't know much about my car, help please e-mail me at www.travmitchell123@aol.com :
