A defective vacuum line can cause a whistling sound when the vehicle is accelerating. A loose belt can also create a high pitched whistle sound.

What cause an engine to miss while accelerating?

An engine may miss while accelerating due to several factors, including a malfunctioning ignition system, such as worn spark plugs or faulty ignition coils, which can lead to incomplete combustion. Fuel delivery issues, like a clogged fuel filter or failing fuel pump, can also cause a lean mixture, preventing the engine from generating sufficient power. Additionally, problems with the air intake system, such as a dirty air filter or malfunctioning mass airflow sensor, can disrupt the air-fuel mixture, leading to misfires. Regular maintenance and timely diagnostics are essential to address these issues.
