rough idle

[Archers]

hey guys just wondering is there any easy way to increase the revs on a vz v6 175kw exec? it sits about 500-550 and shakes and vibrates but when u increase the revs very slightly it stops the problem, any input would be great

prob best to hook up a scan tool to see if any of ur cylinders are misfiring 1st before doing anything else. let us know how you go

idle speed is computer controlled and non-adjustable unfortunately.
