So last week I was driving my new 04 cobra that I've had for maybe 2 months now and it started lunging forward and overheating while I was driving. I made it home and the car wouldn't turn back on until it cooled down. I replaced the thermostat and everything seemed to be fixed. Now this morning on my way to work the car died on me while I was driving at maybe 30 mph approaching a traffic light. I pulled over and my dad came and we jumped the car and it started right up, but now I have no power steering or brakes. I don't really know what is the problem or if the two cases are connected in any way. Any one else have any similar problems or think they know whats going on?
