what should I check/replace for this problem. Miss-fire on cyl 3 (I read the code). It does it most of the time and is a little better when warm, but still does it.
inspect the spark plug and replace if needed and check the compression.
BTW, what kind of ‘mini.’ Year, make, model? Knowing that might help those from group 2.
Thanks. Make/model in title, year 2013, 26,000 miles.
