Fuel injector cleaning (With additives like Liquimoly)-Can be done as DIY (Check rates with service centre and then decide whether to DIY or at there)
A complete Injector Overhauling(Its required when you feel injector is conked off,this method is a hit or miss,can work in some cars,while in some its worthless)-In injector overhauling the injector is removed ,cleaned and mechanically repressurised and reinstalled(There are some centres in Kochi ,some Bosch centres will do the same)
Better to replace injector if budget permits and note once one injector starts failing,others also will be in line to get replaced (as the other injectors get burdened with load of the failing injector)
Slightly off topic injectors of different brands -Ford Fiesta and all has injectors made by Siemens ,Bosch.So contacting them during replacement is also beneficial for injector replacement.
