What does it mean when your car idles by itself?
The most common problem is a faulty fuse. In modern vehicles, engine idle speed is most often controlled by the idle air control (IAC) motor. This can be impacted by bad fuses in many different electronic systems in your car. Next, your high idling could be caused by a computer malfunction.

Why does my intermitten engine keep revving?
The throttle is electronically controlled in this car, but the actual throttle plate itself sometimes can hang up if there’s dirt on it. So if you’ve been driving along and then you come to a stop, the throttle might hang up and not close completely, causing the engine to stay at, say, 2,000 rpm, rather than returning to idle speed right away.
When does the car over revs and jerks?
When I’m driving, sometimes the car over revs and jerks w… After awhile of driving, the car sometimes revs high (like when you give the car gas when it’s in neutral) I usually let go of the gas until it catches back (if you get what I’m saying) it usually happens around second gear at about 2500 to 3000 rpms.
What happens when you rev your engine too much?

Why does revving an engine waste so much gas?
Does Revving the Engine Waste Gas? Yes, revving your engine can waste gas because it makes your engine work harder than it would at idle. Your engine will be most efficient and use the least amount of gas while at idle. So anytime you rev your engine to the high rev range you will be using more gas than you would if you let your engine idle.
