Hi

I've tried to disconnect the O2 sensor.... It was better but this evening, the problem has come back !
So I tried to disconnect the MAF sensor...... the problem is less important, but still here
But, actually, now i don't feel anymore theses small hesitations during acceleration ... I just have some strong vibrations and hesitations between 1000 and 2000 rpm. But it only happens from times to times......
Sometimes, no problem at all !

I will disconnect the knock sensors .......
