Oil from the filter has contaminated the MAF. You can buy a can of MAF cleaner or you can clean it with electronic component cleaner. If you haven't done this before, you have to be very careful that you don't break the tiny and brittle wires or you'll have to buy another MAF. Run a search and you'll find tons of posts on cleaning procedures.
You can use K&N's cleaning kit. Keep the cleaning solution away from your paint and off your hands. Don't use a brush on the element surface. Never, ever use heat to dry the air cleaner. Clean it at night, rinse it thoroughly and let it dry overnight (away from a heat source). LIGHTLY re-oil the element. I follow the creases and hold the oil spray can about 9" away from the surface. The oil will look spotty but it will "wick" into the fiber over time and work it's magic, keeping dirt out of the intake air.
Take your time and do it right.
HTH,
Chris
