@c123pk you are right all the dirt from the fuel tank would end up in the injector filter basket which the fuel filter can not stop...but thats not the only reason the injector gets clog , the problem could begin from day one (ASNU – fuel injector diagnostic, testing, servicing and cleaning). the other reason for clogging is that in pakistan we give very poor quality of petrol so when we turn off our car's engine, the last drop of petrol evaporates on the pintle of the fuel injector, leaving behind varnish and other deposits. Then it keeps on collecting and Over time the injector starts to clog and leak. 10 percent clogging in the injector can make the injector to malfunction and cause any or all of the symptoms like
