Q: Rough idle.

asked by on

My engine is idling roughly.

A rough engine idle could be caused by a few different things. Misfiring, fuel issues, and engine timing to name a few. The first place I would recommend starting would be the ignition and fuel systems. Have a professional do an inspection of these systems to ensure that the fuel is reaching the engine properly and that the ignition system is burning the fuel properly. If any issues are found in these two systems they will indeed contribute to a rough idle. Have the problem fixed as soon as possible to avoid future engine damage.
