While driving the fule regulator pump cracked causing all the fuel in the vehicle to spill all over the hot engine and fumes to come into the vehicle. The car was easily able to catch on fire.
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.
