One of the main reasons a 2019 Ford F-150 might produce a whistling sound during acceleration is likely due to a vacuum leak in the intake system or intake gasket. Another possible source of the noise could be a leak in the breather tube connecting the air filter box to the intake. Symptoms of issues with intake manifold gaskets include engine misfires, reduced power, acceleration, and fuel efficiency, along with other performance problems. The estimated cost to replace an intake manifold gasket ranges from $190 to $540, while labor costs can vary between $170 and $420. The gasket itself is relatively inexpensive, typically priced between $20 and $120.
