Hello everybody !
I've found my problem !!!
before I've just cleaned the injector by hand with gazoline...
I tryed too by loading the 450 FSE Map, because I though it was an ECU problem but the result was the same ... no good
Yesterday ... an idea to clean the injector by a better way,
so I went to see a friend who have and electrolisys sytem in his garage ... (it's correct ?)
That was the solution just mounting it and the engine is so well !!!
It's a beguiner error
... I learn everyday !
So I'm very happy.
Thank you for all and if anyone have any question on the quad Gasgas Wild HP 2007, he can ask me of course !
Regards,
Jerome
