Whats the idle speed during morning starts when the engine is warming up.

When i start my car it idles at 900rpms in Park. When i put it into Drive no matter if the car is warming up or not it will drop to 650rpms. So what can cause this and what is the correct warm up idle speed?


I tried searching to no avail.

Thanks

Sounds like it's within norms relatively. You could clean your isc if you're troubled about it, but as long as your temps rise to normal fast and don't overheat you should be golden with those #'s.

I just thought that would be one of the easiest things to check when not idling good, but you've got that covered.
