Yes, long-term driving with a bad ignition coil can cause:

Unburnt fuel entering the exhaust system

Catalytic converter overheating o r clogging

Oxygen sensor damage

Several Pakistani owners reported cat con failure soon after unresolved coil issues, especially those delaying repairs o r using poor fuel additives.
