Setting idle rpm

    My manuals are packed away from moving recently. The idle speed on my
    97 SL-1 AT has creeped up to around 900rpms over the last few years.
    Could someone briefly tell me how to lower the rpms?
    Sure would appreciate it.
    TIA

    The IAC valve controls the idle. It could be bad or in need of a
    cleaning or you could have a vacuum leak somewhere.

    Don't think you can, it's all computer control. I believe there is a
    low speed stop(keeps the trottle open a little), but nothing to change
    the idle.

    Might want to break out those manuals, for real advice.
