Abstract
An engine idle fault control system that identifies a source of rough idle in an engine includes a first module that monitors an idle speed of the engine and that generates a rough idle signal, and a second module that monitors a fuel control parameter. A third module determines a source of rough idle based on the fuel control parameter and the rough idle signal.
