My Vita is misfiring due to injector one which is continuosly non-stop spraying in fuel. I have changed the injector, but still not solved.

Check injection plug with a noid light. If active all the time and not pulsing with the engine running, check continuity of wiring back to the PCM and if that is okay PCM will probably be faulty.
