Engine stalled while the car was in a moving motion. A cracked case of the breather sensor damaged idle air control valve and blown the fuse for the engine sensors. This is a very serious problem. Luckily, I was not on high way and running 65 miles a hour. My son and I would be killed. Without warning, one failed sensor blown other engine sensors' fuse that on the same circuit. No doubt there is an electrical designing problem with this kind car.
