What causes the Jetta engine to shake?
2 Answers
Jetta engine shaking may be caused by: 1. Engine misfire; 2. Worn or loose engine mounts; 3. Carbon buildup in the engine; 4. Fuel system malfunction. An engine is a machine that converts other forms of energy into mechanical energy, which can refer to either the power generation device or the entire machine including the power unit. Jetta is an automobile brand under FAW-Volkswagen Automotive Co., Ltd., a joint venture of the German Volkswagen Group in China. Its body dimensions are 4501mm in length, 1704mm in width, and 1469mm in height, with a wheelbase of 2604mm and a top speed of 200km/h.
After driving Jetta for so many years, I've encountered engine shaking several times myself. The most common cause is worn-out spark plugs - either aged or with incorrect electrode gaps can make the engine tremble. If the shaking is severe and accompanied by noise or slow acceleration, it's likely an ignition coil issue. Replacing a set doesn't cost much. Avoid prolonged idling during daily driving as it easily causes carbon buildup leading to more faults. Regular oil and filter changes with scheduled maintenance can significantly reduce such problems. Engine shaking isn't just annoying - it may shorten engine lifespan. Procrastinating repairs will only make them more difficult and costly. Get professional inspection at an auto shop early to save both peace of mind and money.
