What causes a slight shake during idle?
I noticed an ever slight vibration at idle when stopped at the lights today. It idles at 550 rpm in drive and at 700 rpm in park.
I changed the idle air control valve just a couple days ago. It did this idle vibe prior to the IAC valve change..
Anyone know what gives ?
Changed them 2 1/2 yrs ago. There isn't more than 10 000 miles on them.
Maybe the carbon that was cleaned from the throttle body a couple months ago, mucked them up ??
Black crud was emitted from the exhaust during the cleaning....
Cats were somewhat clogged too !
Changed those to brand new Magnaflow's.
I don't think you'll get a perfect smooth idle. Engine are run very lean at idle for emissions. You could always try a KAM reset and see if the computer re-calibrating will help.
