So I have been having an intermittent P0300 code popping up seemingly at random when idling. I have replaced coils, plugs and cleaned the ground. Doing this solved the initial problem of a misfire under high load but the code changed from a P0303 to a P0300. I have also had a shop look at vacuum lines to see if that was the issue. They replaced a vacuum pump and called it a job well done. Furthermore, I have cleaned the MAF and intake. None of these things have solved this code popping up.
if you have any suggestions they would be greatly appreciated. I will try to be as active as I can on this thread so feel free to ask any questions. This is my first car and as such I am a novice armed with YouTube videos. Here is a freeze frame of the code.
