Engine problems with KIA Picanto 1.1

First of all, I would like to leave a little hello here and for your time you need now to read my confused thoughts and perhaps also to say thank you. It’s about a Kia Picanto 1.1l Bj.04 (petrol) The engine control lighted up for longer, but without any changes in the driving performance characteristics. It also happened once again for a week from then again a few days. Now it comes unfortunately, after my last ride, not spared, highway, The control lamp suddenly started to flash. Other apparent errors, it obviously only ran on three cylinders. Problem solving from me: new spark plugs, no changes. Ignition cable checked, no change candle picture viewed: Cylinders 3 and 4 are the candles wet, no combustion, or hardly. Ignition coils viewed, are divided, unfortunately exactly the wrong cylinders. The both ignition coils are broken like a lotto sixer, I don’t get that either… ! He is now standing in the workshop and there they are also not smarter than me. Diagnosis box connected, hundreds of errors. It is also somehow clear if the car runs only on 2 to 3 cylinders. Crankshaft screw has been replaced after engine damage. I hope one of you has heard of this car before.
