Hello all .
The viano is running rough .
Idles ok , my star says all the cylinder speeds are more or less identical . it got a kind of a knock though almost like a cylinder isnt firing proper;ly
Its rough to pick too ,does a knocking thing before it gets spinning .
got new oil / fuel filter / air filter .
no leaky injector seats . even swapped injectors for some used ,but with some test certificates ?
just not sure , star says most things in tolerance .
only thing is air mass is just above the upper limit .
any clues fellas
