Yes, driving with a faulty ignition coil can cause:

Catalytic Converter Damage: Unburned fuel may flow into the catalytic converter, potentially damaging it.
Spark Plug Fouling: A weak spark can lead to spark plug fouling, which further affects combustion.
Poor Engine Timing: Misfiring can disrupt engine timing and cause rough engine performance.

Ignoring the issue can lead to expensive repairs, including the replacement of the catalytic converter and spark plugs.
