Hello, I recently changed my spark plugs and coils and it keeps shaking. I'm confused it shows codes P300, p001, p002, p003, and p004.

Hi,
The P0300 is a multi-cylinder misfire. The remaining codes don't exist, but I have a feeling they should be P0301, P0302, P0303, and P0304. Is that correct?
If so, that indicates all cylinders are misfiring. I'm surprised it's running if that is the case.
If they are all having an issue, it is likely the result of a single issue.
Do you ever smell fuel? Is there any smoke from the exhaust? Have you checked to make sure there are no engine vacuum leaks?
A vacuum leak would be where I would start checking.
Here is a link that explains how it's done:

Let me know if I'm correct on the codes. They should be a letter (P) followed by four digits.
Take care,
Joe
