A vacuum or whistling sound in a Toyota Previa while driving could indicate a few potential issues. It might be related to a vacuum leak in the intake system, which can affect engine performance. Alternatively, it might be caused by worn or damaged weather stripping around the doors or windows, allowing wind to enter the cabin. It's advisable to have a mechanic inspect the vehicle to diagnose and resolve the issue promptly.
On a Toyota Previa, the vacuum pump breather pipes are typically located near the vacuum pump itself, which is usually mounted on the engine block. You can find the vacuum pump on the driver's side of the engine, toward the back. The breather pipes will be connected to the vacuum pump and may run towards the intake manifold or air cleaner. For precise location and routing, consulting a repair manual specific to your vehicle model is advisable.

If your Toyota Previa engine cuts out, it could be due to several factors such as a faulty fuel pump, clogged fuel filter, or issues with the ignition system. Additionally, electrical problems like a failing alternator or battery can cause the engine to lose power. It's also worth checking for vacuum leaks or sensor malfunctions that may affect engine performance. A thorough diagnostic check is recommended to pinpoint the exact cause.
