Injectors on a Nissan Sentra, or any other Nissan can become blocked as a result of excess dust and dirt. Small bits of debris can escape the filtration process which normally takes place at a gasoline refinery or factory. Nissan vehicles are fitted with their own filtration system that catches debris that has gone unnoticed at the refinery. The filtration system becomes less effective over a period of time, therefore, it is necessary to clean the injectors on a regular basis. This is usually carried out using a fuel injector cleaner.

Check the fuel injector cleaner to make sure it has not been tampered with, then carefully open it, making sure to not spill any on the floor.
Switch off the engine and locate the fuel filling cap. Unscrew it to detach it from the vehicle. Make sure you put the fuel cap in a safe place to avoid losing it, as you will have to replace it once you have finished cleaning the injector.

Pour the required amount of fuel injector into the fuel tank and allow it to run through the fuel system to effectively clean the fuel injector. Wait for 10 or 15 minutes before turning on the engine.
Look inside the fuel tank, to make sure the cleaner has gone down the hole. Take a fuel pump and fill the fuel tank with gasoline, make sure the fuel tank is full. Switch on the engine, leave it running for 10 to 15 minutes.
