So my discovery 2 TD5 auto is blowing white smoke and misfiring ive changed the injector wiring harness and the fuel filter and air filter and ive changed 1 injector that i thought was the problem but its still the same , when i plug the diagnostic into it while its running injector 2 says 'out of range' does anyone have any idea what could be the problem it doesn't lose any water or oil and ive checked the ECU plug and thats ok ???
