How to identify a Hyundai Kia faulty ignition coil which is causing an engine misfire?
- Turn off the engine. Unplug one of the first coils. Start the car and see if that changed the way the engine runs. If the engine is running rough, that means that the coil you just unplugged is GOOD. Unplug all coils one at a time. When you come to a coil that makes no difference whether plugged in or not, that coil is BAD.
