Last night, it started doing this. I just recently changed out the fan belt which stopped the fan squeal. Every now and then while idling though, it would make a constant chirping sound. Don't know if that means it needs to be loosened or tightened.

But the main problem is that when i started it up, left it in park and revved the engine kind of quickly, it would make this high pitched squeal that i found out was coming from the area around the intake. I also put it in neutral and revved it slowly and it squealed at higher revvs. But after a while, when it warmed up, it wouldn't do it anymore.

So, what makes it squeal at quick and high revvs other than the fan belt?
