Hello everyone I really need help too figure out what’s wrong with my car. I have a 2014 Chevy Malibu LT 2.5L it has an issue where the stop/start kicks in when I sometimes stop it shakes most of the the time but every one In awhile the stop/start kicks in but won’t turn the car back on. After it turns off completely I try cranking the car back on but it just struggles to turn over I would have to press the gas to give it power too turn on. The Malibu has 120k currently I bought with 89k miles I don’t think the previous owner changed the spark plugs but I also think it might be the starter. Please help
