2003 Chrysler Voyager
 

My Chrysler Voyager 2003 automatic idles at 5000 rpm at 100klms per hour.how do I adjust idle

Welcome! But SIR you don't have an Idle adjustment to make...you have a MAJOR PROBLEM!

You don't adjust the idle of modern computer-controlled engines. The computer controls the idle speed. You are not "idling" at 5000 rpm. You have not specified gas or diesel. They are different. I suggest you post your question in the Voyager and Town & Country area of the forum, further down the front page and see if anyone there can help. Specify your engine when you do. In the meantime, check your throttle linkage to make sure the linkage is working properly. Also check for a major vacuum leak if yours is a gas engine.
