Service Engine Soon
Had this light come up the other day. Read the code and it was P0300 for a misfire with the cylinder. I felt like that wasn't happening at all from Joe the car drove. But anyway, I figured it's possible it could be a spark plug by chance. But 1-2 days later the light shut back off and it hasn't came back on since. Why would the light come on and then go back off?
