Engine Makes Crackling Sound When Accelerating Hard

[Trudy]

Engine crackling sound is caused by excessive carbon buildup in the engine and fuel quality issues. Specific reasons: Lack of maintenance may lead to excessive carbon buildup (excessive carbon in the engine, throttle body, spark plugs, etc.). Low-purity gasoline can also cause this issue (as impure fuel tends to form carbon deposits inside the engine). Delayed oil changes or using low-quality engine oil (motor lubricant) may also result in this problem. Solutions: Visit a repair shop for cleaning or replacement. During the warranty period, repairs or claims are free, including diagnostics which can be handled at authorized 4S dealerships.
