The Fuel Injector in Dodge Nitro automobiles plays a very important role of accurately spraying the fuel into the engine cylinder in order to create a correct air to fuel mix for combustion. This system works under the control of the ECU, this controls the timing and quantity of the fuel injected depending on the load the engine is pulling. Some details, common for all the Dodge Nitro models include the use of a returnless fuel injection system, which means that there are fewer fuel lines in the car. The injectors can in one way or the other develop a problem such as blockage or leakage hence resulting into poor performance, low power output and high fuel rate. To ensure the internal parts of this engine are not damaged, replacing faulty fuel injectors, inspecting or replacing faulty injectors frequently, is recommended.
