Finally I found the issue!
the problem was the alternator!
at idle I had 14,5 volts and with car stopped it had almost the same voltage at high rpm
one day I saw WideBand very rich so I had to turn the screw on the ECU to fix it
i didn’t know why
i took a voltmeter, measure my battery’s voltage and I saw 11 volts with my engine at idle
the problem with my alternator was mechanical and not electrical
the strange thing was that my battery light on dash didn’t work at all
i bought another one and now the problem is fixxed
now I have an other problem but this is for a different post
