What Causes Severe Engine Shaking After Driving Through Water?
1 Answers
Severe engine shaking after driving through water occurs because when water enters the vehicle, a small amount of water may seep into the high-voltage wires, and the engine air filter element may also get wet. This leads to increased air intake resistance and water entering the combustion chamber, resulting in poor ignition system performance. In severe cases, the spark plugs may fail to ignite, and the vehicle may even stall. Here are some precautions for driving through water: 1. Accelerate through water: When driving through water, shift to gear 1 or 2 in advance and maintain high throttle to pass through. If the water level submerges the exhaust pipe and the power drops significantly, avoid shifting gears midway and keep the throttle high. After passing through, stop the vehicle in neutral, rev the engine a few times to expel water from the exhaust pipe, and then press the brakes several times before driving again to ensure they function properly. 2. Neutral gear and throttle: If encountering obstacles while driving through water, the driver can shift to neutral and press the throttle to maintain engine speed, avoiding deceleration to prevent water from entering the exhaust pipe and causing stalling. If the engine stalls during the process, do not attempt to restart it or tow the vehicle in gear. Instead, tow it back to the repair shop in neutral.
