[QUOTE=Cloud Kim;8360821]my car mileage is 128000km.
change all of spark plugs and coils at 127000km
My car shake at idle repeatedly. this symtom is not regulary. but when shaking happens, my room lamp's led light trembles and alternator voltage get dropped... at this time, I push accelator up to 1000 rpm. this shaking symtom is clear and light is no more trembing..also alternator voltage get to 14.7V
Even if I change all of spark plugs and coils, my car sometimes occur misfire on cylinder no.4 when driving over 100km distance.. this problem occured on cylnder no.4 repeatedly.
When I checked CAM magnet and shaft sensor, it looks fine without oliy.
Base on upper symptoms, there is no more error on OBD2. Is there any idea or experience like this problem? Remove and clean MAF sensor and throttle body if you haven't done so already
