I'm from Malaysia. I bought a used 350z (2003 version) in Feb'13. At the beginning, there was a problem with the engine vibration and the mechanic had rectified it by replacing the ECU.
Soon after that, there is a bigger problem arised - the engine dies off automatically few second after starting. Then got to try a few times and rev up the engine simultaneously, it runs smoothly after that. But once the car is idle for few hours or every morning, this problem occurs again.
My mechanic has already done the engine relearn via computer, checked the mass air flow sensor, converter, but still cant solve it. Do you have any glue?
