I already did some overhaul change the gasoline check the OEM replaced the fuel pump spark plugs clean the injectors. The timing in DOHC is perfect. I started it and the engine continuously misfiring. I pulled out the number three connector on the injector and the engine was not dead and continue to misfire it has no reaction. I do the same at number one it is the same too. But number two and four has the reaction when I pulled out the connectors the engine shuts off. Can you tell me what is the problem? I really appreciate it thanks. By the way here in my country it is Ford lynx GSI. Its the same engine with Mazda Protage or 323. It is a zmde engine.
