Thank you rasmataz, I will do the tune up. Just as an addition, the reason I suspected something else is because the van isn't running any different( rough or sluggish) but fairly normal. Now once in a blue moon it will idle at a higher RPM but usually back to normal when van is turned off and restarted.

Clean the idle air control valve out and see what happens.
