What are the reasons for severe shaking in a Volkswagen 1.6 engine?
1 Answers
Volkswagen 1.6 engine shaking severely reasons are as follows: Engine misfire: Engine misfire mainly refers to one or more cylinders in the engine not working properly, usually manifested as intermittent exhaust gas flow from the car, severe shaking of the exhaust pipe, and noticeable engine vibration, sometimes accompanied by a sputtering sound. This is mostly related to ignition coil failure. Engine mount rubber aging or loosening: Engine mount rubber refers to the rubber blocks placed between the engine and the car frame. Their function is to reduce the vibration and shock during engine operation and to secure the engine in place. Once these mount rubbers age or loosen, the engine's shaking becomes significantly worse. Replacing the mount rubbers will greatly reduce this effect. Carbon buildup issues: Cars are inevitably prone to carbon buildup, which includes cylinder carbon deposits, throttle carbon deposits, spark plug carbon deposits, and intake carbon deposits. When there is excessive carbon buildup inside the engine, the car's ignition energy, intake efficiency, and air-fuel mixture ratio are affected, leading to unstable power output and noticeable shaking during idling and acceleration. It is recommended to visit a 4S shop for an engine cleaning service. Fuel system failure: Using an incompatible fuel grade can reduce the car's power output and performance. Alternatively, if the fuel tank cap vent is blocked, or the fuel tank switch, fuel filter, or fuel lines between the tank and carburetor are partially clogged, the required fuel supply may not be met, resulting in a lean mixture and engine shaking. It is recommended to use the manufacturer-specified fuel grade and perform regular maintenance.
