How loud was it? If ur talking about the injen evo 7300 I had the same issue after taking the box in and out several times . Which caused the 1 or all 3 rubber washers located in the location where the air box snaps and seats on the engine bay.. without those, the hard plactic box vibrates on the metal of the car... i think thats ur problem . I bought those rubber washer for $3 ea on ebay... its like $8 each at my locale gm dealer. About the light ive never had a light may be there a leak sowhere....
