    Car stalling, jerking and sudden death

    I have checked the inertia switch. When engine is cranking the inertia feed cable before switch-12.92v & 12.84v after the device. The O2 sensor reads 0.1-0.3v. The sensor failed other tests. I would have it replaced and run the car to confirm.

    Car stalling, jerking and sudden death

    Car has one O2 sensor. Socketed in place. What readings are expected? Voltage or ohms?
  3. Hi, my 2005/2006 Ford focus hatchback car developed a stalling, jerking and sudden stop problem after installation of a catalytic converter and for 5months running. I have changed the spark plugs, ignition coil, fuel relay, used 9fuel pumps, changed slow jet, changed air collector, used 2 fuel pump casings, inner & outer fuel filters and changed the brain box all to no avail. I have also washed my fuel tank from clogs. Diagnosis displayed error codes PO230, P1100 & P720. Please, what could be the possible element that reduces voltage to the pump thereby overheating it 20-30minutes after working or when the A/C is turned on?I took voltage readings for the battery, relay, inertia switch, alternator and fuel pump. When engine is idle, battery-12.48v & cranking-13.5v. When engine is idle, alternator-12.49v & cranking-13.77v. When engine is cranking, Inertia feed cable before switch-12.92v & after switch-12.84v. When engine is cranking, fuel pump-12.6v & during the stalling, jerking & sudden dead situation- fuel pump-11.6v. The problem is intermittent. it occurs at odd times. Sometimes 20times in a day, sometimes twice, 3times, 40times, but it sure occurs. One cannot predict especially when the A/C is turned on. What are your thoughts on this please?
