I keep getting the P0300 CEL whenever I'm driving slow on first gear. I have changed the plugs and the car is still throwing the code.

The car is acting normal and I can't see anything wrong with the car, except that after changing the plugs I can feel the car smoother. I have 15k miles on the car.

Stock injectors and stock fuel pump is on the car

Any solution?

Check where your LTFT/STFT are.

I had also random misfire when I had unproperly tuned the car and STFT were jumping around 20%.

I have stock injectors, so STFT/LTFT shouldn't be a problem.

Many other things can throw your trims off.
