It depends on the size of the engine and the number of cylinders it has. An eight cylinder could idle between 550 and 850 rpms while a four could be between 700 and 1000. It is possible that the rpms could even be higher, but that again depends on size, cyl, and year it was made. The best way for you to answer this question is to look in the owners manual if you have one. If you are lacking the manual, ask at a local parts store. The people at the auto parts store are always happy to help because if the car is broken, it could mean a sale for them. Just remember to bring the following information for them. Make of car (Ford, Chevy, etc.), model of the car (Mustang, Impala, etc.), year it was made, the size of the engine (289 cubic inches, 2.2 liter, etc.), and the number of cylinders. Good luck!
It is normal for a GMC Sierra to idle fast when it is first started. It will idle at around 1500 rpm until the engine warms up. To get it to slow the rpm's sooner, a person can tap the throttle once and it should slow down.
A typical idle speed for a normal car engine is 600 rpm to 1,000 rpm. It is higher for buses and motorcycles. RPM stands for revolutions per minute.
Idle speed will vary from 600-1000 rpm.Idle speed will vary from 600-1000 rpm.
engine idleing to slow turn up your idle to 1500 rpm at idle drive safe
Idle speed is computer controlled between 500 and 1500 rpm. It is not adjustable.
Throttle plate sticking? Vacuum leak?
Simple, in D or any other forward or reverse gear you are putting a load on the engine by activating the transmission. N or p are neutral gears that put no load on the engine and that is why you can take your foot off the brake in either one. The question is what is the normal idle rpm of your vehicle? If it is out of range then it must be adjusted.The normal idle RPM of Neon is 1000. It just went up to 1500 when I stop at the red light yesterday. It was 1500 rpm on both N and P. It's never been like this. I think something is wrong.
when the engine starts and is warming up the idle is supposed to be at around 1500 rpm but when the engine warms up the idle should drop to between 700 and 1000 rpm. if it doesnt drop then see a mechanic because it is a very complicated fix
Engines that run generators don't normally idle. As soon as you start one, the engine immediately comes up to operating speed, usually 1800 or 3600 RPM for North America, and 1500 or 3000 RPM for Europe. There is a governor that keeps the engine at this speed. It does have an adjustment, but this is for normal operating speed, not idle. Many models of portable generators have manuals that can be downloaded. Check the manufacturers website.
Sounds to me like this might be due to your A/C cycling on and off if you have it set to defrost. It does this to dry out the air that it routes to the windshield so that it can more effectively de-fog the glass. When the A/C engages, it puts load on the engine, and thus the RPM must increase to keep it at idle.
