    Default IAC steps??

    Burb seem to idle fine...although takes a second to find idle at times when starting.
    Can someone tell me if the IAC steps seen in this log look normal?
    I've been reading that I should be around 60? I see mine are closer to 20 when around 75+oC???

    Thanks

    YOU ONLY NEED TWO TOOLS IN LIFE - WD-40 AND DUCT TAPE. IF IT DOESN'T
    MOVE AND SHOULD, USE THE WD-40. IF IT SHOULDN'T MOVE AND DOES, USE THE
    DUCT TAPE.
    IF YOU CAN'T FIX IT WITH A HAMMER, YOU'VE GOT AN ELECTRICAL PROBLEM.

    It is never getting to 0 in the log so there is still room for the IAC motor to step out further. I'd probably aim to have them around 40 though at full warm idle.
