I have this unstable/shaky sound (idk how to explain it so I uploaded a video to YouTube with the sound) while accelerating. I thought it was something to do with the car not being warm but I still have it 40 minutes into a drive.

Thanks guys! Any help is appreciated.

Has it lost power? How's the idle? Also check engine codes.

Doesn't seem like it has lost any power, it idles at around 800 it seems but makes like a faint thud sound every few seconds at times during idle. I will check its engine codes.

My previous engine had a deep knock at idle. Timing belt was out a couple of teeth.

For anyone that might come across this post in the future, it turned out that one of the valves is misfiring :(
