I have a problem with a Seat Ibiza 1.0 MPI (80 HP) 2019 (mileage 96,000). While driving, the engine starts jerking, regardless of whether it is warmed up or not. I connected VCDS and each time it throws errors P030200 - misfire detected (cylinder 2) and P036300 - misfire detected - fuel supply off. The EPC light comes on. Today it happened twice that after such an action I could not start the car.
Additionally, I checked with VCDS and found that the camshaft adaptation "stands" at a value of 5.1 degrees. I checked the camshaft adjustment and when I checked the exhaust string, the camshaft adjustment changes as the camshaft adaptation, and on the intake side the camshaft adjustment changes and the adaptation "stands" at a value of 5.1 degrees.

Can you tell me where to look for the problem?
