What Causes Engine Shaking and Exhaust Pipe Abnormal Noise?

[AsherMarie]

Engine shaking and exhaust pipe abnormal noise can be attributed to the following reasons: Engine Misfire: Engine misfire primarily refers to one or more cylinders in the engine not functioning properly. Common symptoms include: intermittent exhaust gas flow from the vehicle, severe shaking of the exhaust pipe, and clear audible sounds from the engine such as "popping" or "thumping" noises. This phenomenon is often closely related to ignition coil failure. Overly Rich Air-Fuel Mixture: When the engine's air-fuel mixture is too rich, the symptoms include: difficulty starting the engine; poor acceleration after starting, uneven engine operation; black smoke from the exhaust pipe accompanied by popping sounds from the engine, sometimes even backfiring; decreased engine power and increased fuel consumption. These issues are mostly related to carbon buildup, clogged filters, etc.
