With misfiring and rough running you might need a fuel system flush/clean. There is a system that has been on the market for a few years that plugs into the fuel injection. You disable the fuel pump and run the car on the chemical flushing system, it cleans all the injectors with one chemical then cleans out the carbon build up from the combustion chamber through to the back of the exhaust with another. It takes about an hour and costs about £75 to £100 depending on engine size/number of cylinders.
I have an 8 year old 110,000 mile Nissan and had mine done at the Nissan dealer (here in Saudi) with a Bosch System, it made the engine run smoother and made a measurable improvement in the emissions.
