Hello folks, I have a DS3 Racing with 207hp 1.6 4 cyl Thp engine.
On diagnostics monitor it shows me on cylinder 3 an injection duration of 10ms on idle. 1, 2 and 4 only have 1ms. on cyl 3 it goes a bit down to 8-9 ms after revving and letting it go down. the engine runs quietly, but i can feel a little shaking from time to time.
I use Autocom for diagnostics.
No error codes.
What I found out and tried so far:
Cleaning the engine with verylube
Changing ignition coils and spark plugs.
Use cleaning additives in the petrol.
I checked with an endoscope and intake valves have a lot of carbon residue. Piston also some left even after the cleaning process.
Does anyone have any opinions?

Andreas,
Safe to say if one cylinder was receiving 10x the fuel of the other 3 cylinders, the engine would sound and run terribly.
My guess is there's an error in the monitor itself, perhaps it's off 1 decimal place and 10 is actually 1.0 ms.
You could purchase or borrow an oscilloscope so you can measure the actual injector on times to verify what's happening.
