ever sense i started driving this car(6-7-8 months ago) the car has had this buzzing sound comming from the engine bay. and its gotten worse ever sense. now it only happens at a lil about 1750 rpms((right about 45mph in 4th which sucks because that the main speed limit around here)) now the only way to describe this sound is like a person who has a sub in their trunk and the entire trunk shakes. like vibrations of metal on metal but its has a deep tone. today i got home put the car in nutral and reved up to that point and it sounds like it deffanetly is comming from the engine bay.
its a 94 ex auto

help!

 

Its the 1800 buzz, common problem on older Hondas. It has to do with a poor heat shield design near the cat. Honda has an anti buzz solution that works for a little while. I wouldn't recommend ripping the heat shield off, you will have a fire hazard.

 

whats this anti buzz solution?
