Is it bad to rev engine in neutral?
Yes, this causes engine wear. When the transmission is in neutral and the engine is “revved” without any load, the spinning engine internals will accelerate, gathering rotational and lateral forces at a faster rate than designed by the manufacturer. Rapidly revving an engine will heat up the piston rings much faster.

How do you stop sudden acceleration?
Resolution. Ways of resolving sudden unintended acceleration are to apply the brakes and/or clutch, or shift into Neutral if the car has an automatic transmission. In most cars, fully applied brakes are easily capable of stopping the car while the accelerator pedal is also fully applied.

What happens if you rev a car in park?
Valve keepers have been known to get kicked out, letting the valve drop far into the cylinder and cause serious damage. So, revving the engine, if it has accumulated wear, can be destructive to the engine. It may sound great, it may cost you.
