I was driving and my engine was sputtering so I safely stopped and could not find the issue, it rattles when the gas is pushed, it also smokes when the throttle is pushed, I don't know what the issues is whatsoever.

Can you please shoot a quick video with your phone so I can hear the noise? That way I can tell for sure what's going on. You can upload it here with your response. It sounds like you have a fuel pump that is going out or a clogged catalytic converter. I would start by changing the fuel filter. Here is a generic guide to help you step by step with instructions in the diagrams below to show you how on your car.

and this guide as well, you can rent a fuel pressure gauge at the auto parts store:

FUEL PRESSURE
At idle:
Approximately 235 kPa (2.4 kg/sq.cm, 34 psi)

A few seconds after ignition switch is turned from OFF to ON:
Approximately 294 kPa (3.0 kg/sq.cm, 43 psi)

Here is a guide to help you check the cats.
