Car stalling, jerking and sudden death.
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?
