hi all, my 93 lwb vitara decided to idle really bad today. for some reason it idles at a fixed 800-900 rpm as per normal but there is a very bad wobble in the motor that shakes the entire car. if i try to rev it up it has a bit of a lag - starts off with a loud empty 'note' before revving up, also the revs sounds pretty gutless - sounds hollow/empty. drove it that way to the local shopping center. it wobbles during acceleration and feels pretty weak and gutless. wobbles on cruise too just a little less. i think it wobble more during lower revs (Acceleration). i suspected it was the airflow meter. looked around here and found other posts regarding airflow meter and their airflow meter is different from mine. mine is the one that has a cone on both ends and the side that faces outwards (air filter) moves in and out to allow air to go through. i took the airbox out and let it idle while fiddling with the cone and it actually idles properly w/o wobble if you help push the cone in a little from the side. so i need some advise as to see if it really is the airflow meter thats causing the issue, like a bad fuel to air ratio maybe? |

have a good look at all your intake and vacuum hoses for a split, and eay way to do this is spray some carby cleaner or wd40 around the hoses and it the idle speed picks up thats where the leak is |

thanks for the advise. but i just dont get it. it keeps its rev at idle. idling speed is regular. i just think its missing or some sort. does anyone know how to check the ecu fault code on a g16B motor? will it show up in the faults? thanks |

sent car to the mechanic to change lower control arm bush. got him to do a scan. turns out to be a bad ignition lead on cylinder 3. changed the whole set of leads and spark plugs and car runs sweet~ thanks for all the advises here again, will keep in mind on diagnose of vacuum hoses~ |
