My van has a rough idle when cold, but engine warms up it runs fine. I did tune-up recently to help the problem but it still has the same issue. Any help would be fine. No check engine light on either.

Check for trouble codes anyway, they may be stored even if the light isn't on. Check for vacuum leaks and try cleaning the idle valve and the throttle body.
