[QUOTE="DILLARD000, post: 1045852, member: 74901"] Do you have any OBD2 TroubleCodes? 500rpms is too low for WarmIdle; should be 650~700rpms. Suspect you've got a vacuum leak somewhere. Once its warmed up with Engine idling & AC+Heat off: ~ set MinimumIdleScrew on right side of ThrottleBody so Idle is ~700rpms ~ unplug IACValve, RPMs should fall & Engine should sputter & may die. If RPMs do NOT fall then you DO have a vac leak.
