Immediately at fault recognition

TROUBLE SYMPTOM:
Engine keeps running at higher revolution than specified idling revolution.

--------------------------------------------------------

Here are the steps if you want to do the step-by-step inspection yourself before taking it in. If you recently changed your air filter, check your air box and see if it is seated correctly. It can be that easy or adjustment of throttle cable, loose or cracked vacuum lines, cracked gaskets or worst - idle air control solenoid.

1. Check for loose installation of intake manifold - particularly the unit that house the air filter

2. Check for cracks on intake manifold

3. Check for cracks on gasket of throttle body

4. Check for cracks on gasket of idle air control solenoid valve

5. Any vacuum hose disconnected or leaking?

6. Check throttle body cable for excessive play

7. Check the bypass air line for foreign particles that can clogged the system

The most common cause on the newage is the idle air control solenoid valve sticking. It's a very common fault on them.
A good clean with petrol or brake cleaner type solvents along with some cotton buds soon sort it out. It's only 2 screws to remove and you will soon see if it is that or not, they are usually full of black gunk which cause it to stick.
There's plenty of tutorials about if you google it. Main thing i would recommend is that you get a new seal for it before you remove it. It's a formed o ring type seal and as soon as it's disturbed it won't fit back in it's recess.
