2000 Mercedes Benz ML320 6 cyl All Wheel Drive Automatic 59800 miles
My MB ML320 all of a sudden developed a misfire. The computer code P0300 shows cylinder 2 but other cylinders have also misfired. I checked one of the two plugs in cylinder 2 and it is clean and normal. I replaced the mass air flow sensor about a week before this new problem started. With the miss there is a general lack of power but particularly under load. The car runs fine at 80 mph but does not accelerate. Any ideas?
