I have noticed that when I travel faster than 80 mph on the freeway, I get a loud buzzing noise that I believe is coming from the my injectors. Its the same sound you hear when doing an injector buzz test with a scan tool.

Curious if my injectors are going out or if anyone else has had this?
 
Pull valve cover and just make sure all the connecting nutz are tight...

Other than that, I have never heard of a "Buzz" under the hood..
