Crusing at about 75mph on a busy freeway , my cars rpm bounced up then dropped down to 0 , the car became stiff and turned off. i had to cross 3 lanes at about 20 mph and pull over on the shoulder. the car would not turn on until about 30 mins later , i had to drive home with no power steering. i later find out it was an error in the ecm and it is an electrical issue
