Between 650 rpm and 750 rpm, depending on the year, engine load percentage, A/C on or off, & electrical load. Another factor is type of IAC. (idle air control valve) Best way to check proper idle is to monitor IAC function with a scan tool. Reading should be aound 35%. If IAC is lower, but idle is higher, you probably have a vacuum leak.
