If it makes a hollow sound, itâ s probably empty. If your ignition system is faulty, your engine will abruptly shut off, causing your car to shut off while driving. AlternatorIt really freaked me out, especially as I was going around 70 on the highway. However, about 15 minutes later it happened again, but this time the speedo went to zero then back up again. I don't think the engine shut off, but it was enough to get me to pull over. I turned off the car and restarted. It didn't happen again all the way home.
Start it the third time and it starts right up and idle drops to 750 and remains absolutely constant. Then the same issue happens a couple of more times while I am driving on a highway but I just pop it into nuetral and it cranks back up with minimal speed loss. Each time the guages act funny prior to the engine turning off.
