Hi,

I have a rough idle, and i started by checking each injector, so i loosened the nut at the injector, on each one, to see what it does.

Well, i figured that number 3 doesn`t care when i loosen the nut for it, so, i tought, it must be that one, so i replaced the nozzle on it, put a new heat shield, and so on.

Surprise, same problem afterwards. The injector still doesn`t seem to work...

Filters are new, the inline, and the metal one...

Can you guys point me on the right path ? Cause i don`t know anymore

Thanks
