I was seating in a tacobell drivethru, when all of the sudden my engine had a catastrophic engine failure.
My 2000 Ford Focus with 70080 miles suffered engine failue while at highway speed. The engine will not remain running unless the accellerator pedal is held off of idle. The engine will not crank and stay at idle without operator intervention. The unit has been removed from service pending repair. There is a rumbling sound from the right front of the vehicle and the steering wheel shakes (+-0. 5" at 3 hertz) when at 55mph and above.
