This is what it means when the car engine hesitates. It is usually the result of a problem with the air and fuel mixture within the combustion chamber.

Why is my motorcycle not accelerating at high speeds?

More firing is performed at higher speeds whereas slower speeds have less firing. The engine timing is the mechanism that controls this. If you have poor timing advance, spark plug firing becomes delayed and isn’t timed right which will cause your motorcycle to not accelerate properly. This will probably be accompanied with some backfiring.

What happens when engine RPM drops below 800?

However, when the engine RPM drops below the normal range of 800 RPM (for most cars), it is more than likely that you are dealing with an IAC valve problem. In cases where this valve is clogged or is failing, your vehicle will stall instead of slowing to an idle after the release of the throttle.

What causes car RPMs to go up but not down?

There might be a leaking vacuum hose in the car, hoses deliver air and fuel to the combustion chamber. If it is leaking, the air will mix with the gas causing the RPMs to go higher than it should be. Another thing to look out for is a clogged air filter if the air is having difficulties entering the combustion chamber.
