What Causes the Engine Yellow Warning Light and Car Shaking?
1 Answers
Reasons for the engine yellow warning light and car shaking: poor combustion of the air-fuel mixture, spark plug failure, and abnormal pressure. Poor Combustion of the Air-Fuel Mixture: When the air-fuel mixture in the cylinder is too rich, the vehicle may experience knocking and shaking. If the mixture is too lean, the vehicle may exhibit poor acceleration. Solution: When the engine warning light comes on and the car starts shaking, immediately stop the vehicle and call for a tow truck to await assistance. Spark Plug Failure: If the issue is not with the air-fuel mixture, it could be due to problems with the spark plugs, high-voltage wires, or ignition coils. Poor performance of the ignition system or weak spark plug firing can also cause the engine warning light to illuminate and result in shaking and insufficient power. Solution: If such a problem is detected, check for any abnormalities in the spark plugs and have them inspected thoroughly at a professional repair shop. Abnormal Pressure: This can be caused by abnormal fuel supply pressure or a faulty intake pressure sensor. Incorrect fuel pump pressure or erroneous readings and poor performance of the intake pressure sensor can lead to car shaking and power loss. Solution: First, stop the vehicle immediately and check if the engine oil level is sufficient, then proceed to a professional repair shop for maintenance.
