Update
I will try to take a picture of the oxygensensor values and other interesting readings on the Bosch system.
A short summary: The car idles bad. Deviating with a hundred or so up and down from about 800 when cold. When hot the idle is from 1200-1400.
Have changed plugs, checked coils, cleaned maf, switched throttlebody with both sensors, replaced a broken rubber sleeve and checked multiple times for vaccum leaks in the engine compartement. Changed fuel filter and air filter, engine oil and filter.
Both old oilfilter and plugs looked in good condition.
Car still throwing random codes on misfire, on different cylinders each time.
It pulls strong when on heavy throttle, but misfires on light throttle and idle.
Next is AOS. Ordered today.
A thought came to my mind. After deleting codes and driving for 70km I hit the brakes hard to test them. The CEL immediately came on again. Could I have a vaccum leak in a brake booster hose or something? Just a thought.
