    i guess, that AIR bypaas screw ti adjust idle RPM.... its factory set n never to be touched....

    if u reset ur ECU by disconnecting battery....ur idle rpm shud be 700-750 according to factory spec...

    Thanks

    But i've seen mechanics often setting these, right now it is fully closed.
    What's its actual position -fully closed or few turns, if open then how much turns?

    bro...first of all im not an expert...

    in Pakistan, santro launched without RPM guage, wat abt ur santro? does it have RPM? or r u using aftermkt one? or any scanner to accuratly set RPM?

    if its a air bypass screw on the throttle body, then u can increase idle rpm by opening it and reduce by closing it.

    first u must ensure that all other settings are according to factory spec, then moniter rpm on a warmed up engine, if different from factory specifications both with n without ac, u can adjust by opening or closing that screw...

    then disconnect battery for 10 15 mins reconnect n check again

    Thanks bro
    Me too not expert
    No rpm guage
    It is air byepass screw, even if it is set, ECU detects it and make changes accordingly.
    So wot's factory setting?
    m mostly concerned about if it is fully closed or not?

    ps - if rpm are not correct local mechanics adjust this hearing engine rpm

    just like how a Hakeem can detect any ailment by feeling the pulse of patient....u must consult its Service Manual for factory specs, search over net...i never had any santro so i don't knowi cant understand how can an human hearing organs translate sound of engine into exact RPM reading....if possible then its amazing...u shud ensure.....the throttle stop screw has never been touched...if already moved then its kinda tricky to adjustthe tps working properlyiacvs correct duty cycle by check pulsethen monitor idle rpm...and adjust bypass screw to maintain correct rpm

    OK, car was revving on higher rpm and guy just turned that screw for low rpm. Later discovered it is fully closed.
    If it is not settable, why its there with so many turns? Even seen *** guys setting them.
    Anyone knows its setting? Factory setting?
    I saw them doing this on bikes, mine also, amazing average.

    I never saw this screw in our local assembled models. So no comments.

    Air byepass screw, it is there in manual image.
    No mention of it's working or setting in workshop manual
    Xulfiqar bhai's comments required

    Edit - let me rephrase my question - local mechanic disturbed setting of air byepass screw and I want to restore it back keeping idling speed at normal.

    We don't have this knob in our local santro. you can check a new santro of some friend or nearby, and adjust yours accordingly.
