I would check the air filter and if it is okay. Let's do a fuel pressure test because it sounds like the fuel pump is weak. Here are two guides that can help us with instructions on how to change the fuel pump in the images below:

and

Fuel Pressure
Fuel pressure at idling .................... Approximately 350 kPa (3.57 kg/sq.cm, 51 psi)

You can rent a fuel pressure gauge from the auto parts store for cheap or free. Also, we should run the codes as well.

This video can help you drain the fuel:

Here is the fuel pump for $51.00:

Check out the images (below). Let us know what happens and please upload pictures or videos of the problem so we can see what's going on.

Forgot to add that it's throwing codes P0300 and $0010. Not P0010 but $0010. Thanks you, I'm changing the filter today and checking the fuel pump.

I know you said $0010 which is not a code? Could it be the scan tool is having an issue?

P0010 - "A" Camshaft Position Actuator Circuit (Bank 1):
