    1,000 rpm @ idle is not all that bad. Have it tested for a possible vacuum leak or tampered with throttle stop screw. Check engine light on? Possible idle air control problem. If that screw has the 'paint' seal broken and has been turned, it is possible someone turned it to mask another idle problem that needs to be checked by a mechanic with a scanner.
