Hyundai Repair Questions? Ask a Mechanic for Answers ASAP
You will need to get a scan done of the vehicle, particularly the ECM, (engine control module).
Can you get this done please?
If the engine is misfiring, due to a faulty coil, spark plug, or injector fault, the engine will run rough and illuminate the warning light.
Do you still need help?
I hope my advice has been of assistance to you.
