Question type: Maintenance & Repair

I have a 2008 Ford Fusion SEL with the 3.0L  (118K miles). What could be causing codes P0300, P0304, P0305, P0306 and P2197.  The car shakes and rattles while running.  These issues happened suddenly while driving to work in the morning.  There is no power and the break pedal will intermittently go to the floor.  I have changed spark plugs, the oil is clean.

good morning, p0300 is random misfire, and p0304,p0305,p0306 is cylinder 4,5,6, misfire codes that is the 3 cylinders on the frt. bank, to lose a whole bank, is normally caused by a timing concern or excessive back presure, for example a plugged catalytic converter, my sugestion would be to take it to a dealer and have it professionaly diagnosed, we could play the could be game all day. ima senior master tech, at a ford dealer

well those 3.0 are the worst about clogged cats so don't be to hasty to spend big bucks @ a dealer that could care less how many parts they hang on your car.take it to a muffler shop.and ask them to check and see if ANY of the cats are clogged it is a big problem as well if it is low on power..then a good chance,there clogged and most muffler won even charge..and if they say it is not..they are clearly telling the truth cause they don't make a penny.by not selling you any thing..then you might take it to a reputable macanic..don't have to be a dealer....
