Idle is computer controlled and no way to increase it. May want to make sure the throttle body is clean. Use carb cleaner and a soft tooth brush to remove carbon buildup.

Don't think there's anything wrong with it. That's pretty normal for mine. If it's unusual behaviour for your car, check your coolant level. I almost ran mine dry last year and found in the days leading up to it that my idle revs were sitting around 2000 once the car heated up. If it turns out to be that I can give you some real handy tips for changing your coolant and flushing all the junk out. Much cheaper than a mechanic and good if you have a spare hour.

Idle is factory set and cannot be adjusted, your best bet is checking for cracked hose pipework for air intake at idle,(not at problem under exceleration and driving) Any slight upset to the air /fuel ratio will be most prevelent at idle speeds.Check hoses where the meet metal flanges on manifold intakes and any sharp bends in ppipes.Good luck
