for the past week my engine,upond start up, makes makes this loud air flowing noise. but i can't tell where its coming from, it seem to be from the throttle body but it wasn't, i clean it up and the noise went away for a day then came back. i do have a weapon r intake for over a year and never had any problem with it. any ideas?

 

did you check for any leaks in the hoses, tubing of the intake?
