Ok.
Thanks.
i will try this setting for sure.
I think i found the problem : i have removed all the injectors because it sounded like it was choking itself after to have checked again all the stuff i did yet : belts TDC etc....
I found 2 MOFO STUCK INJECTORS : the needle is stuck in the nose for 2 of them...
i'm cleaning them right now and i try to unstuck the two bastards without fubar them
If you have any advice to do it properly i 'll take it !
