Idling Low

[cardr69]

I 2004 Silverado with a 6.0 ltr, put a new alternator on it and now it seems to be idling too low, any ideas. Thanks

what is it idling at. check your connections and your grounds.

Have you driven it much since changing the alt? Your ECM will begin a relearn process since you pulled the plug on the power while working on the alt. Drive it for a while and see if it improves. Check all your connections as well
