When To Change Fuel Injectors
Fuel injectors work by precisely supplying the engine with the exact amount of gas it needs, at the best possible moment so that it can ignite and keep your motor running. Some manufacturers like to suggest that their fuel injectors are built to last the life of your car, but with so many variables, like the cleanliness of the gas you fill your tank with, it is impossible to say that with certainty.
How to Prolong the Fuel Injectors Life Span
There are certain steps you can take to help keep your fuel injectors healthy:
How Can I Tell That My Fuel Injectors are Bad?
Misfiring is the main symptom of clogged fuel injectors. This is when the engine is not getting any type of power from one or more of its combustion chambers. Your vehicle will be sluggish and possibly idle roughly.
Dirty fuel injectors are sometimes stuck in an open or closed position. One that does not open will make it difficult for you to start your car and you will experience a general lack of power from your engine. An injector that will not close due to a build-up of debris will cause your car to lose fuel pressure and allow gasoline to enter the motor oil sump. You can verify this by smelling the oil on the oil level dipstick. If you can detect a gas smell than you know that one of your injectors is leaking fuel.
Flushing the Fuel Injectors
Before making the big decision to replace the fuel injectors, you can try flushing them first. Although this is a job that can be done at home, you do need to proceed with caution. Cleaning the fuel injectors involves opening the fuel line, so make sure that you are in a well ventilated area free of anything that could cause a sudden spark.
When is Cleaning Fuel Injectors Not Enough?
An overheated engine or over use can cause cracks to form on the body of the fuel injector. If cleaning them did not help improve your engines performance, then you may have to consider this as a possibility. At this point you will have no alternative but to replace the fuel injectors.
Before getting started, you will need to purchase a new set of injectors for your car. It makes no sense to go through all of this trouble to only replace one or two fuel injectors. To ensure that the fuel injectors you purchase will meet your vehicles OEM standards, buy them through CarPartKings.com.
Like cleaning the injectors, replacing them is hazardous due to the exposure to gasoline. Before you decide if you want to take on the project yourself, be sure that you have a well ventilated area to do it in. Again you will have to disconnect the fuel pump and run a U hose back to the gas tank, but replacing the fuel injectors also involves disassembling the fuel rail. Once you have that removed you can access the fuel injectors.
Fuel injectors play a massive role in the way your car runs. It is responsible for the power, efficiency and even the amount of emissions released by your engine.
