Tried the $8 Walmart cold air intake mod on my 2002 Civic and the CEL came on before I left the driveway

I grabbed a cone filter and some dryer duct from Walmart for $8 and rigged it up to the stock intake tube in 20 minutes flat. The car started and idled like it just got a cold, threw a check engine light, and then ran worse on the test drive than it did before I touched anything. Anyone else try this cheap intake trick on an older Honda and figure out how to make the MAF sensor stop complaining?
