Here is what is said about the codes:

P025C: This code refers to an issue with the fuel pump module communication circuit.

P0300: This code is a general misfire code, which means that one or more cylinders in the engine are not firing correctly.

P0301: This code specifically indicates a misfire in cylinder 1.

P0302: This code specifically indicates a misfire in cylinder 2.

B210068: This is not an OBD-II error code and I could not find any information on it. Can you please confirm the accuracy of this code?

So, it looks like you may have a fuel pump going out and a fouled or worn spark plug. How does the engine run? Can you upload a video of the problem?
