What Causes Unstable Engine Idle When Turning the Steering Wheel While Stationary?

[OFaith]

Here are the detailed explanations for the causes of unstable engine idle when turning the steering wheel while stationary: Unstable Oil Pressure: If the fuel pump's supply pressure is abnormal or the intake pressure sensor's readings are incorrect and malfunctioning, it can cause vehicle shaking. The solution is to check the oil pressure and replace components if necessary. Ignition System Issues: If there is a malfunction in the car's ignition system, it can lead to poor ignition system performance, inadequate spark plug firing, and other issues, resulting in unstable engine idle. The solution is to inspect the condition of the spark plugs, high-voltage wires, and ignition coils, checking for excessive carbon buildup on the spark plugs. If found, clean or replace the spark plugs immediately.
