Like I've said, probably multiple times on the forum, those two separate P219 cylinder problem codes you're throwing are fairly serious. Most things I've seen online say to not even drive your car.




Hopefully you and your mechanic can pinpoint the issue. And like I told you privately, there's a lot of potential causes.
