Hello friends. Today, while I was driving on the highway (110 km/h), even though I wasn't driving too hard, my car suddenly started losing power with a fault code (catalytic converter fault). When I pulled over, I noticed that the engine was running rough. When I tried to take off, it vibrated heavily. Even though I could barely get going, it continued not to use gas. I slowly arrived home. But I don't have a clear idea of the cause of this problem. Note: The car's engine is vibrating a lot while running and making a clicking noise. The exhaust is also making a popping noise. (The car doesn't have an overheating problem.)
