Check that the intake didn't come off of the intake manifold. While I really doubt that is the problem it's worth a shot. Also you might want to take a look at the exhaust system. Check the piping and the muffler and everything and make sure that there are no holes in it or that it's not rusted through anywhere. One of my friends used to have a 93 Accord and part of his exhaust was rusted through and it sounded something similar to what I imagine yours sounds like. That's probably my best guess of what it is. Especially for a 124k miles... depending on the weather where you live and how the previous owner drove it... just might be the case.
