What should my idle be set at?
In most of today’s cars, an idle speed of 600 to 1000 RPMs is average. If your car is idling rough, though, it won’t feel smooth. The RPMs will jump up and down, for example, or they’ll fall below 600 RPM (or whatever is typical for your vehicle).
What RPM should I set idle at?
650 RPM
Turn the idle screw to adjust the idle—turn the screw to the left to increase the RPM or to the right to lower it. When you have adjusted the idle—aim for 650 RPM—reconnect the idle air adjustment valve’s electrical connection.
How do I reset my idle speed?
You can reset the idle air control (IAC) valve by turning the car on, putting the car into park, pressing the brake down, then pushing the gas pedal down, counting down about 5 seconds, turning the car off, waiting 10 seconds and start the car again, checking to see if the car is idling properly.

Is it normal for a car to idle at 1500 RPM?

How do I know if my idle air control valve is working?
Take your multimeter and set it to “Ohms.” One multimeter lead should touch one end of the valve terminal, and the other lead should do the same for the other end. The normal reading is between 0.00 and 0.05. Anything outside of this means your idle air control valve is bad.
What causes rough idle at low rpm?
The most common cause of rough idle is a vacuum leak or a failed PCV valve. It could also be caused by other air-fuel mixture-related issues like bad fuel injectors, EGR valves, or low compression. In rare cases, it is caused by misfires from a bad spark plug or coil.
Why does my car idle at 500 RPM?
Most of the time this is caused by either a vacuum leak or a dirty throttle body. I would then check the throttle body and clean it if needed. This is probably the most common problem.
