Your Saturn fuel injectors are far more efficient than the carburetors that motor vehicles used to be made with. In their continuous efforts to provide ever more efficient fuel usage, which not only stretches the gas dollar, but also benefits the environment, Saturn has used Saturn fuel injectors in three different types of fuel injection systems since 1991. These were the throttle body injection system, the multi-point injection system, and the sequential fuel injection system. Naturally, Saturn fuel injectors that are functioning well are essential to the workings of any fuel injection system. The attention that Saturn devotes to their fuel injection systems reveals just how important the process is to the overall performance of the vehicle. And that is exactly why your Saturn fuel injectors should be of great importance to you. If you do not pay attention to the maintenance schedule for your Saturn fuel injectors, you can expect poor gas mileage and a general decrease in performance, including difficult and less reliable starting, rough idle, rough running, and less power, due to a decreased ability to accurately respond to the fuel demands of the engine. When you delay changing your Saturn fuel injectors, you run the risk of damaging a variety of other parts within the fuel system, as well as those affected by the performance of the fuel system, such as sensors and even your catalytic converter. It's just not a gamble worth taking when you tally up the potential costs of the other parts in terms of both time and money.
