Fuel Injector Check
- Connect tachometer to engine. Run engine at idle. Observe tachometer, and disconnect and reconnect injectors individually. When disconnected, each injector should cause a momentary drop in engine speed of at least 100 RPM. Engine RPM drop should only be momentary, as PCM will attempt to re-establish correct idle RPM.
- Replace any injectors which do not cause sufficient drop in engine speed. When test is complete, check idle speed. Refer to emission control specifications on decal in engine compartment, or see IDLE SPEED in ADJUSTMENTS - 2.0L article.
