1996 Chrysler Concorde Question: How do I adjust the Idle
Answer #1Bret Bodas from RepairPal Test Shop, April 13, 2010, 18:03Master
Most vehicles don't have idle adjustments, so if you start trying to make adjustments you can create more problems. This should have an idle valve that controls the idle speed, and a throttle position sensor that is used to determine when you are idling. Check these and diagnostic codes first, and look for any vacuum leaks too.
