Jitter: poor fuel injection causes the engine to run out of balance
Decreased engine performance
Jitter: poor fuel injection causes the engine to run out of balance, and noticeable vibration will be felt in the steering wheel and body. Decreased power: Unstable fuel supply results in sluggish power response during acceleration, which is particularly noticeable when overtaking or climbing a hill. Increased fuel consumption: poor fuel atomization and inadequate combustion, resulting in more fuel being required for the same distance. STARTING AND RUNNING PROBLEMS
Difficulty in starting: In case of severe damage, it may not start or may suddenly stall while driving. Abnormal tailpipe gas: unburned fuel is discharged through the exhaust pipe, forming black smoke with a foul odor. Long-term effects
Excessive tailpipe emissions: inadequate combustion leads to increased emissions of harmful substances. Increased carbon deposits: Poor fuel atomization aggravates carbon deposits inside the engine, which may further damage the cylinder, piston and other parts. If the vehicle shows the above symptoms, it is recommended to check the fuel injector status and clean the carbon deposits in time. During routine maintenance, you can clean the fuel filter regularly and use qualified fuel to reduce the risk of clogging.
