I have a 2015 gen coupe 3.8 manual transmission,

car has trouble starting up and has trouble staying running won’t idle on its own without using the gas pedal to keep the rpm up.

codes are : p0300 - p0517 battery temp - p0703 brake switch B circuit - p0905 gate select position circuit

any ideas where to start? Spark plugs are completely black so I’m changing those first and seeing if this helps my car run better. Any other ideas where to start looking would be appreciated!! Thank you guys!
