The fuel that resides in your gas tank has to be carried to various spots of the engine to be burned and used to power the vehicle. Making sure that the fuel is being delivered properly should be something that you take very seriously. Normally, the fuel from the tank will travel through lines to the fuel injectors to be dispersed. Each of the cylinders in the engine will have a dedicated fuel injector. The fuel will be dispensed in a fine mist, which makes it much easier to use and burn during the combustion process. Every time you crank and run your car, the fuel injector will be used to provide the engine with the power it needs to perform.

The fuel injectors on your car will typically last between 50,000 and 100,000 miles. The length of time that the injector lasts has a lot to do with the type of gas that is used in the car and how often the various fuel filters are changed. Using lower grade gas will usually lead to the fuel injectors becoming gummed up. There are a number of injector treatments on the market that can help to break up these types of deposits. Eventually, even the treatments will not be able to get the injectors back in good shape and they will need to be changed out. A bad injector can wreak havoc on an engine and will have to be replaced immediately to restore functionality.

The fuel injectors are a very vital part of your engine and without out them the proper amount of fuel will not be delivered. The last thing that you want to do is ignore the warning signs that the fuel injectors need to be replaced due to the damage it can cause your engine.

When the fuel injectors are in need of replacement, here are some of the things you will start to notice:

  • The Check Engine Light is on
  • Your engine continuously misfires
  • The fuel efficiency of the car begins to decline significantly
  • You detect fuel leaks around where the fuel injectors are mounted
  • There is a noticeable gas odor coming from the vehicle

Getting a quality fuel injector put back on your car will be worth the money spent due to the performance it can provide.
