idle problem,opinions?

[mike991]

so recently my idle has been acting up,it keeps dropping below the one on

my RPM gauge mostly during the day,at night there is no problem. weird i

know. anyways when the idle gets too low when i gas it there sometimes is

a tiny squeal? any ideas what this might be,. please and thankyou

I used to live in Pembroke Pines...15 yrs ago. Is it a squeal or a hissing sound? Most likely a vacuum leak somewhere. Have a shop perform a smoke test on your engine. If it is a squeal then check the belt to the alternator. It might be loose.
