Is it bad to rev an automatic in neutral?

No. It may actually be a problem for the drive train. … Many automatic transmission won’t go into gear if the engine speed is too high. So if you rev up the engine in neutral, and shift the transmission into gear, you might just sit there in neutral until the RPMs come down enough for the transmission to engage.

Why is my engine revving in park?

The idle is controlled by the idle air control valve and if it cannot keep the engine idling it will keep trying to rev the engine up to compensate. A vacuum leak, sensor that has failed, or an EGR system malfunction could potentially be the cause of the erratic engine you’re experiencing.

Will revving damage engine?

Revving the engine won’t speed up the process. In fact, that could cause easily avoided damage. Cold revving causes abrupt temperature changes that create stress between the engine’s tight-fitting components.

On a modern electronically fuel-injected car, absolutely nothing happens at all when you press this while parked. The fuel systems are controlled by the engine electronics, and are not active until the engine starts running. … Pressing the gas pedal releases some of this into the engine.

What causes engine to rev up and down?

Erratic engine idle can be caused by various factors, but the most common and likely cause is a dirty or malfunctioning Mass Air Flow (MAF) sensor. This is a device found in fuel-injected cars and measures air flow so that the appropriate amount of fuel can be injected.

Why is my car revving but not moving?

Q: The car is revving but not moving properly This may be related to a couple of different things such as low transmission fluid or a faulty transmission control module. As you may know, automatic transmissions use pressurized hydraulic fluid to change gears.

What are the symptoms of a vacuum leak?

Since a vacuum leak similarly lets air into the engine, the engine will respond by idling faster. When this happens, the car’s computer will try to compensate, typically creating a sporadic or fluctuating idle speed. The engine stalls: In some cases, a vacuum leak can cause your engine to die or stall out.
