Q: Car idling rough

asked by on

The car is idling rough. It shakes really bad, sputters, and then shuts off.

A rough idle indicates that your engine is misfiring. There are many reasons why a car would misfire. It could be a bad ignition coil or spark plug. It could also be a bad control module or wiring issue. If any of these problems got bad enough it is possible that eventually the car would shut off. I would have a qualified technician inspect your vehicle’s components and diagnose your car’s rough idle.
