Idle RPM

[Buddyshelton]

Anyone else think their idle RPM is too fast ? Mine is 850 RPM. Let my foot off the brake and it accelerates to 4 mph on its own.

That's about right.

yeah, you don't see many 4 cylinders idling much lower--the vibration would be horrible.

If it's in D, then it's going to start moving on its own if you take your foot off the brake.

Thanks for the replies. I just felt it was a little fast and my dealer said it could not be adjusted. I don't think i believe that.

Just the right speed to keep from stopping in "stop and go" traffic - if you leave a little room to the vehicle in front of you.

Good point

Fuel injected engines cannot idle much lower than that.

I've never seen one less than that.

This is the nature of a 4 cylinder engine. A v8 can idle at 5-600 and be smooth. But for every rotation they have twice as many power strokes to smooth things out.
