No, I haven't checked the exhaust specifically. What kind of noises should I be listening for? And what did it end up being for you?

Well, in my case, it turned out to be a small leak in the exhaust system, causing the engine to misfire. The symptoms were almost identical to yours. If it is indeed the exhaust, I would recommend taking it to a workshop. The repair cost me around 265€, but it's better to be safe than sorry, especially if it affects the timing belt. Don't drive it too much in the meantime.

Thanks a lot for the info! I'll definitely check the exhaust and get it to a workshop asap. The error memory also pointed to a leak in the exhaust system. Seems that you had the same problem. I really appreciate the help!

Interesting. I have a Mistra too, and I had a similar issue a while back. The jerking and the check engine light are dead giveaways. I initially suspected the ignition coil or even the fuel pump. Have you checked for any unusual noises coming from the exhaust?
