Just recently, my car has thrown a check engine light. Cylinder 2 Misfire and Cylinder Misfire on start up. It doesn't happen every time, but sometimes when I start my car, it will have a really choppy idle for 10-15 seconds, then go to normal. Also, when hitting any boost, it sounds like a misfire/cutting out. I don't have any engine mods besides some drop in filter and the catback exhaust the car came with. I also just filled up my coolant last week to the maximum line, and it's already back to the minimum line. I'm almost 99% sure it's a head gasket, but I wanted to see what others think. I've read online that when this happens to people, the shop ends up coming back and telling them that they need a new engine. I also heard that it's such a common issue with these cars that there's a law suit against Ford for this faulty engine design. I have an appointment in a couple of days to get it checked out, but won't replacing the head gasket just result in the same thing later on eventually because of the poor design?
