This has been a problem for at least 4 months now with this car. Its a 1991 Accord EX-R, and whenever it's being driven you can hear a weird squeaking noise coming from under the hood. It sounds similar to a turkey gobble. I'm thinking it might be a belt but the problem is it never makes this noise while idling with the hood up. My mechanic hasn't been able to figure it out, he thought maybe a motor mount but that didn't help any. Any ideas/suggestions? Thanks!
