It'* fine. A car'* IDLE needs vary depending on temps, plug conditions, and such. Say it gets any higher, then I'd worry a little about a problem.
Some run at -10, some a little above. Mine'* a little above, 8ish. Sometimes it goes to -10 at idle.
If it has changed, you can try spraying TB cleaner at/near vacuum lines and connections for the EGR. If the idle ever changes, it would show a vacuum leak. If the idle gets down below 1000 when warm, it wouldn't be a bad leak, but I'd look into fixing it anyway.
