Clogged Fuel Injector Symptoms

Most car owners find it quite the task to analyze and diagnose the health of the car’s engine, as much as it is important to clean the fuel injectors on most vehicles to keep them running smoothly when to clean them might be an issue. It is therefore important for the car owners to understand the various symptoms the dirty injectors show and how to clean them. Understanding these symptoms will give you an opportunity to know when you are dealing with a clogged system and thus you can clean it before it leads to other major problems.

If the vehicle owner does not use any fuel cleaner the fuel injected engine will get dirty and clogged to some extent. The clogging is mostly noticeable for cars that drive for short distances as multiple engine ignitions and shut offs will exacerbate the clogging. Clogging caused by the deposits is usual and unavoidable, it comes with the territory of operating modern fuel injected engines but regular maintenance of the vehicle will prevent the clogging.

Fuel injectors disperse fuel into the engine at the exact angle and quantity needed for the engine to operate optimally, there are several fuel injector nozzles that must evenly disperse the fuel, and in case a single nozzle is affected by dirt from the carbon deposit the engine performance will be affected.  Most car owners replace the injectors that have deposits of the carbon on it though it is advised not to do so as the fuel injectors work in tandem and if the buyer decides to replace one, the fuel injector will be inefficient in its operations. In case the car owner wishes to buy a single injector it is good if she replaces the whole fuel injector, though before replacing it is always good to try out cleaning the fuel injector system using a fuel injector cleaner.

However if the injectors are clogged early symptoms are hardly noticeable since modern cars come with internal sensors and computers that can adjust the fuel mixture to compensate for minor errors. When the clogging gets too severe for the car engine to adjust, the engine will suffer from the following problems:

  • Low performance – if the fuel engine is insufficient combustion will be impeded and the engines power decreases. Clogging causes for insufficient fuel supply to the combustion chamber.
  • The car’s engine will begin stalling – The clogging might cause uneven fuel supply during idling which causes the RPM to fall too low and this might result in stalling.
  • Failing emission tests –The clogging causesa decrease in fuel combustion which causes incomplete or uneven fuel burn and this increases emissions that come out through the cars exhaust system. Regular cleaning is recommended as the clogging build up and might lead to adverse engine problems.
  • Increased fuel consumption – More fuel is burnt if the fuel combustion efficiency decreases. The combustion chamber might need to burn more fuel for the engine to work as good; the car owner will end up using a lot of cash to refill.
  • Engine misfire – if the air does not mix properly with the fuel in the cylinder it might cause an incomplete combustion event, this might in turn affect the cylinder directly causing it to miss strokes causing immediate engine power loss and a noticeable sound effects. When this gets severe enough the driver will feel a jerking action from the engine.
  • The engine will begin to shutter and hesitate when the car is started – The carbon deposits will affect the engine and cause for insufficient air and fuel mixture, this will in turn affect the combustion inside the cylinders that might lead to problems noticeable over time. In some cases the car might hesitate starting.

Once the car owner notices any of the above symptoms or all of the symptoms the car owner can resort to trying out fuel injector cleaners. It is however advised to employ the fuel injector cleaner earlier to prevent any of the problems that come with the clogging. You should choose the best fuel injector cleaner with proven results to ensure that your vehicle is operating at optimum levels.
