Common rail injectors
#11
The rail pressure is fine once the engine has actually started, it meets the expected rail pressure when reved up according to live diagnostics. So HP pump must be ok, and even though the rail pressure hits.. say.. 600bar, the pump may be producing a shitload more to get the rail pressure to 600, due to having to overcompensate for the excess leakage.

It's only when near idle rpm where it struggles to reach the expected 300bar - the actual rail pressure shows as 200bar if i keep it near 800rpm with accelerator - as soon as foot is removed, it drops below 200 and obviously cuts out.

Soo.. i've took the injectors out and having a friend of a friend at carwoods check them out for me. Should really have done a leak off test but, well.. i;m just going to take a risk! Shouldn't cost too much to have them properly tested!
