What Causes Car Shaking After Washing the Engine with Water?
1 Answers
Because a small amount of water entered the high-voltage wires during car washing, and the engine air filter element got wet, leading to increased intake resistance and water entering the combustion chamber, resulting in poor ignition system performance. Below are the relevant explanations: 1. Ignition system issue: Check the working condition of the spark plugs, high-voltage wires, and ignition coils. Poor performance of the ignition system or inadequate spark plug firing can also cause such fault symptoms. 2. Unstable oil pressure: It is recommended to have a professional repair shop check the fuel supply pressure and whether the intake pressure sensor is functioning normally. If the fuel pump supply pressure is abnormal or the intake pressure sensor values are incorrect or malfunctioning, it can cause the car body to shake.
