What Causes Engine Shaking in the Hyundai Elantra?

[StMaria]

The reasons and solutions for engine shaking in the Hyundai Elantra are: 1. Low engine temperature. When the car is started cold, the engine temperature is low and has not yet reached the optimal operating temperature, leading to idle shaking. Simply wait for the engine to warm up. 2. Severe engine carbon buildup. When carbon deposits accumulate severely, they can clog the engine's fuel delivery system, preventing proper combustion of fuel and air mixture, resulting in engine shaking. In this case, it is necessary to clean the engine carbon deposits promptly to avoid other issues like increased fuel consumption or loss of power. 3. Engine misfire. If one of the engine cylinders fails to function, it disrupts the engine's balance, causing shaking. Professional inspection and repair at a repair shop or 4S dealership are required.
