How many RPMs should a car idle at?
For regular cars, idle speed is typically between 600 and 1,000 rpm, just enough to keep the engine’s ancillary systems going, but not enough to move the car forward much.
What should the idle RPM be on a car?
Your engine should normally get to around 700 RPM after you start the vehicle, depending on the model. If your idle is way off and you have one or more of the problems listed above, then you will want to diagnose the issue right away.
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.
How many revolutions per second does a car do when idle?
While idle, the engine will complete about 10 revolutions or more per second. Because of its vast speed, the gauge displays the counts as multiples of 1,000. A vehicle that is operating normally should measure at about 1,000.
What should I do if my car idling is too high?

Is it normal to have a rough idle?
This is definitely not a normal situation. If you are experiencing a rough idle or your RPM is running high, then there are a variety of reasons for why this could be happening. It is not always easy to diagnose the cause because there are so many factors involved here. Below are the top 5 causes that a mechanic would look for.
