injectors were scaled in and been working perfectly for 7-8 months
this problem just arose randomly
the only thing that is different that i can think of is that i blanked the breather pipe on the intake hose and put a breather filter on the breather system. but cant remember if it ran ok before or after that.

If that is the case, literally the last thing you want to do to fix the problem is by changing ECU map values around.

originally i thought it was something i had changed on the map but i switched out the ecu for my backup one and still the same so it has to be a mechanical problem.

So... I changed the breather back and carried out a smoke test, but getting a lot of smoke out the dipstick tube coming back through the breather system.
Is the breather valve thing that looks kinda like a dv meant to be a one way valve? If so mine ain't working.
