Fuel Injectors

WARNING: This page is about a different car, the 1996 Mercury Villager and 1995 Mercury Villager. However, it is still accessible from the selected car via links, so may be relevant.

Connect tachometer to engine. Start engine and allow to idle. Disconnect and reconnect injectors individually. If each injector causes a momentary drop in engine speed of at least 100 RPM, injectors are giving proper fuel delivery. RPM drop should only be momentary, as IAC will attempt to re-establish correct idle RPM. Replace any injectors that do not cause sufficient drop in engine speed.
