what is a normal idle speed at the normal operating temp?
I recently cleaned my throttle body along w/ the IAC valve motor. I was especially careful not to pull the pintle out while cleaning the IAC. After putting everything back, I noticed the idle speed on my YJ is around 650-750 RPM when the engine is warm. Is this a normal idle speed? Other than that, the jeep seeoms to be running very smoothly after the cleaning.

That a good idle speed, and you should put a 195 thermostat in it.

That's lower than what I get... Mine is around 850 RPM (on the dash, anyway!)
