What is the proper way to adjust the idle on swift m13a auto?
Issue is the idling is fine on P or N (about800) but when i put it in D or R, its rpm drops 600-650 and car shakes. The car runs fine over all though but when i am at a stop with brake and in D, the car is shaky. Not much but still shaky. With Ac, it runs great with rpm around 850 in D.
i have changed the plugs with factory recommended plugs i.e. NGK bkr6e11. Issue still remains. Cleaned IAC and TB by myself. It didnt have much carbon and IAC was easily rotating as well.
What i havnt done is ECU reset. Would that help? If so, please guide how to properly reset the ECU in PKDM swift.
Plus in autos, do we need to adjust the RPM by rpm adjustment screw or is it done by ECU itself? I was tild not to fiddle with that screw, however, i think if ecu was responsible for controlling Idle all by itself, there wouldnt be an idle adjustment screw in the first place.
One more query, if we are supposed to adjust RPM through Adjustment screw, should it be done with car in D or P?
PS. Car is 64ks driven. Oil shell 5.40 less than 600 s driven. Air filter is clean. Plugs changed when oil was changed.
