Engine light on running rough on idle and in park hesitates sometimes and growling sound while driving in reverse but still drives forward with the power of when you press the gas pedal

I would start by checking the engine codes to see which ones are stored, here is a guide to help you.

If you have lean codes then chance are the fuel pump is going out. But if you have misfire codes I would start with a full tune up, here is a guide to help as well
