Fuel Injectors

Fuel injectors, located in intake manifold, spray atomized fuel directly toward associated intake valves. All injectors are supplied with fuel from a common fuel manifold. On 2.0L and 2.3L engines, passages in intake manifold feed a stream of air to tip of spray nozzle in order to better atomize fuel at point of injection and cool injectors. Signals from ECM control injection pulse duration. Injectors must not be rotated. Fuel injector connector must point straight up. If injectors are rotated, fuel will hit walls of the intake passages and affect emissions and driveability. If a fuel injector fault is present, closed loop operation will be cancelled.
