Ignition cable defective?

I have a question, but first of all to the car. Omega B 12/94 x20xev The omi has a bit of a jerk. So I worked with the search function through several topics. Quickly was fixed to check ignition cables! The ignition cables are from 1999… total power of the car approx. 270tkm and here are the values 1= 5,84K 2= 5,1K 3= 4,96K 4= 2,48K Are they now due again? According to Etzold 3K – 20K are allowed. After that only one slightly deviates. But if I look at the values e the Axcell has posted here once, they deviate already considerably. Since I drive the omi also once, I have the ignition cable again installed. The sequence checked again and started. It runs now totally bad … much worse than before. He does gas only if I give gaaaanz laaaangsam gas. Easily desperate I have checked the ignition sequence several times and check if the plugs are all sitting. There is definitely everything OK. Did I now build somewhere? Or can this have been triggered by moving the cables? Has this ever happened to you?
