lowering idle speed

[houkster]

No problem with lumpy idle or dying issues. My idle sounds to fast for my liking and tach reads about 900-950 after about 60 seconds of idling. At 1st service tech went the extra mile and synched the throttle bodies, may have increased idle then (about 6 months ago). Local dealer says they've been warned to not adj. throttle bodies to lower idle. Read a bunch of posts. Glad I'm not stuck with a 1200 rpm idle because the factory likes that speed!
Anyone out there had the same situation?

O.K. I'll ask this in a different way. Has anyone out there purposefully lowered their idle speed and if so, noticed any negative effects? (brain misinterpreted this or that)
