Im not exactly sure how to explain this. theres a noise that comes from the engine bay when giving it gas. it kinda sounds like a horn type of noise maybe the IAC? but i have changed the IAC not to long ago. so im not really sure what it is. also it sticks once i change gears. I have a 2000 gt stick with about 111k on it.

Whats sticks? The RPMs?

A bad IAC valve can def. make a hoot/horn sound. Also, aftermarket IACs can also go bad sooner than you think they should.

Yeah the rpms stick. whats a forsure way to see if thats what it is. besides change it lol

Well if you can get it to hang the rpms or make the noise try tappin on it with something metal and see if it changes
