Help removing intake manifold to replace vent hose

Hello...
I have a '96 Grand Am with the 2.4L engine. There is a vent hose running from the timing chain cover to the oil/air separator that I need to replace. In order to get to the hose end that connects to the oil/air separator, I need to remove the throttle body, several other related parts, and the intake manifold.

How difficult of a job is this? Removing the throttle body and stuff sounds like something I should be able to handle, but I'm not sure about the intake manifold. I've never worked on anything like the intake manifold before. If anybody can give me some tips or advice on what to expect and how difficult it will be, I'd greatly appreciate it. Also, how easy is it to completely screw up something like the intake manifold when removing/replacing it?

Thanks!!!

its not to bad to remove the TB and intake.

Just need to remember where everything goes/came from, a picture is always a good idea to have around for the assembly.

I'll PM you a link !!
