What is idle on 4.2 Auto?
Can anyone tell me what the idle of a V6 w/Auto should be in park? Mine is 8-900 and that seems high.

Idle on these engines can range from 600 - 900rpm Mine is right at 820 - 840.

You can get that changed by a chip. When I get custom chip done my idle is gonna be 650... where I want it!

mine doesnt idle that rough, my last emissions test said my idle was at 850.

now you want a rough idle , my moms durango jumps all over the place w/318 and my dads '02 ram is even worse but he has custom flowmaster duals
