Need a little more info as to how long this happened and what might have contributed to it.

Could be many things, most not serious, but some of them are quite so.

Good Luck

You may have tanked some bad gas. Just a shot.

If you can check codes, it should guide you to where to look. I am certain that you have some misfire codes, but you may also have some MAF or 02 sensor issues.

Run the codes and see what you get for "C" codes and not "H" codes. The H is for history or old codes.

Keep us posted

when this sputtering happens put it in neutral but keep pressing the gas pedal and see if the engine stops sputtering.
