How To Tell If Fuel Injectors Are Clogged

The easiest way to tell if your fuel injectors are clogged is to look at the injector itself. If the injector is clogged, there will be a build-up of fuel deposits on the injector. These fuel deposits can cause the injector to misfire, or not fire at all. Another way to tell if your fuel injectors are clogged is to check the fuel pressure. If the fuel pressure is low, it could be due to a clogged injector.
