I'm sitting here at work almost starting to worry about a cracked intake manifold.

Here's why it *could* be cracked.

1. Car is a salvage title with front passenger side impact
2. Engine just sounds "loud" from the interior (new motor mount helped a lot, but this engine is still LOUD anywhere above idle when I compare it to my 2001 GTI 1.8T)
3. Vacuum hoses look great, but I can't get my idle under control.

I'm going to try unplugging the IAC valve tonight to see how it behaves at idle.

Are there any common places where the zetec intake manifolds would crack?

Any help is greatly appreciated
