I do have the idea that my coil was not properly grounded. The snap that I felt really felt as if the coil itself had to snap onto something on top instead of something deeper into the engine. It would also make sense that if you unground one coil, two cylinders are about to misfire and the ecu will shut down the injectors.
If anything happens I will let you guys know. Next time the cover comes off, IŽll exchange the connector bots. I have read about them being troublesome before so better safe then sorry for that money.
Thanks again and greetings,
