MAZDA MPV CATALYTIC CONVERTER PROBLEM

2005 Mazda MPV • 140,000 miles

My 2005 Mazda MPV has a hard time going up hills. I changed the spark plugs and the coils, it helped a little, but it still has a hard time with really steep hills. What could it be?

Check catalytic converter to make sure it isn't plugging.
