Fuel Injector

Fuel Injector:

The fuel injection system on the 3.0L engine utilizes sequential fuel injection in which the ECM independently controls each fuel injector. The ECM grounds each fuel injector circuit for a certain length of time based on engine operating parameters. The fuel control system is designed to maintain a 14.7 to 1 air/fuel ratio under all engine running conditions except deceleration, heavy acceleration and cold engine startup. The ECM can turn fuel injectors Off during deceleration, misfire diagnostics, traction control and during one of the two throttle control system limp-home modes (REDUCED POWER telltale will be illuminated).
