What are the symptoms and causes of a cloged catalytic converter

Posted / edited by AnonymousUser on : 12-11-2018

Answers :

Symptoms are rough running, stalling, poor gas mileage, and especially a strong smell of rotten eggs (sulfuric acid). The main cause is old age, but poor/cheap/contaminated fuel can also be a contributing factor.
