Yes, check it on a level surface with the engine running and the gear shift selector in neutral or park. Check it after the engine has warmed up.
The idle is not adjustable.You have other problems if it's idling to fast are to slow.The throttle plates are calibrated / preset at the factory.Is the check engine light on ?? If it is, then you need to have the engine scanned with a engine scanner to check the emission system and sensors. It will also help your idling problem after you repair the problem that made the check engine light come on. If you don't find your problem in that area. then PLEASE ask your question again.
