“Driving down the road at a slow speed and the car just quits. Sometimes it will start itself back up and sometimes I have to pull off to the side of the road to turn ignition off and then on again. The car will just quit at highway speeds and after some quick thinking and realizing what just happened the only thing to do is drift to the berm of the road with no pwr steering or brakes. There are also times when I start the car it will quit and takes two to three more tries. Also had a severe raw gas coming from the car after a fill up. …”
