Found my culprit

[liquify33]

So on and off I’ve been dealing with P0300 and misfires on 3&4 at highway speed in passing gear. Turns out the culprit was a loose gas cap.

Hope this helps someone else.

A loose gas cap will cause a misfire? News to me.

You didn’t get gas after this started? But hey, if that solved it roll on.

Great to read, even if I do not fully understand the connection between the two. Thank you for sharing!
