The Camshaft Position Sensors are now changed with working used sensors bought from Lextreme (thank you David!) for a really good price. Got 4 used ones (so I have 2 as spare parts) for less then 1 new sensor cost in Sweden. My problems seems to be gone now. But before I got the sensors changed I changed out my MAF with a used one from ebay because when I did the test as seen below I some times couldn't get a reading at all.

And after I changed out the AFM my problems with "jerks"/misfires never occurred again. So can't really tell if it was the AFM who caused them or if it was a combination between bad cam position sensors and a bad AFM. But my check engine light is not on now after the sensors was changed. Overall the cars seems to run a little bit better now.

If the crankshaft position sensor is bad the car would not start.
