so i finally threw a code reader on my car to see why i had a check engine light and came up with P0302, which is a cylinder two misfire, and P1412, which seems to be a manufacturer specific code. any ideas on what this may mean? nearest kia dealer is one hundred fifty miles away so i cant just go ask them. any help will be great! thanks
