Hello guys,
i have this car with vibration fault,the engine vibrate when you reach at stop but is not every time sometime it wouldn't vibrate,it doesn't vibrate when you're driving,no smoke.

i checked the IQ in data measurement the quantity will be under value when it vibrating and the rpm also,but when in good motion all value are ok,i think that the problem should be in IQ.

any idea to fix this fault or by chip tunning,please see attached the bdm file.
no possible to adjust by obd with launch.

thanks

I finally solved the problem,the fault was in ecu files as I suspected,I copied the ori file of another ecu to mine except the S2prom dump which is for syncro with ecu and job done.
