Inlet manifold cleaned and all parts back on car.... still not running right.
Injector leak test done and results are a bit baffling... icarsoft diagnostic scanner continues to report injector no.1 at fault, but makes no mention of injector no.3.
Pictures of leak test attached (no.1 injector is the recon).
I would now be swapping the injector from No1 to No4 and vice versa. If the fault moves, you'll prove it's the injector. If it doesn't move, it suggests the injector drive circuit, or the cylinder down on compression.
Have you had a compression test done? A compression ignition engine (diesel) must have good compression, or misfiring will occur.
