Hey everyone, I’ve got a P0303 code on my Ford, and from what I understand, it means there’s a misfire in cylinder 3. I’ve already checked the spark plug, but the code’s still there. Should I try swapping the ignition coil to see if the problem moves to another cylinder? If that doesn’t fix it, could it be a fuel injector issue or something more serious like low compression? Has anyone else dealt with this on their Ford? For reference, I’m driving a 2009 Ford Fusion. Any advice would be appreciated!
