I was driving home from work early hours this morning and my car jolted abit and the check engine light came on, this is my first time running into any issues with my car so I I’m completely oblivious as to how an engine should look, after having a look, I started up again and now it’s gone, is this a normal thing to happen? I’m abit worried because I have to take a 3 hour trip today and I don’t want to be stranded out in the middle of nowhere away from family and friends
