What Causes the Engine Yellow Warning Light and Jerking Sensation?
1 Answers
Reasons for the engine yellow warning light and jerking sensation include: ignition system failure, fuel system failure, excessive engine carbon buildup, engine system malfunction, and damaged catalytic converter. Ignition system failure: For instance, aging ignition coils or spark plugs that haven't been replaced for a long time can lead to insufficient ignition energy, poor combustion, and weak engine acceleration. When the engine warning light comes on, promptly replace the aging components. Fuel system failure: System malfunction causing low pressure. Insufficient fuel injection can result in weak engine acceleration. It's advisable to visit a 4S shop for servicing. Excessive engine carbon buildup: Too much carbon buildup can impair fuel atomization, leading to poor exhaust combustion, excessive emissions, and weak acceleration. Timely cleaning of the engine is necessary. Engine system malfunction: Engine system failure can cause the engine to enter an emergency operating mode, limiting power output and resulting in weak acceleration. Visit a 4S shop promptly for engine system inspection and repair. Damaged catalytic converter or turbocharger: In such cases, take the vehicle to a repair facility for computer diagnostics to identify the fault codes and troubleshoot accordingly.
