Default 2007 Wrx hose question

So I was inspecting my engine bay today, since I was going to wash the engine bay the next day and noticed a hose being crimped by my bypass valve hose, sorry if that doesn't makes sense, I took a picture to try and clarify my problem.

Anyways I've been trying to figure out why I have a bad idle (going from running to a full stop the rpms would jump around for a bit then stop) or (creeping in first during traffic), (going reverse having the wheel turned all the way one direction) situations like those would set off the jumpy rpm.

I was wondering if this could be a potential culprit and if it was how would I fix this problem?

That looks like the throttle body coolant heating hose. I have not studied the subaru cooling diagram enough to know if that causes any real issue.

Ok so I looked up a few things about the coolant line going to the TB and people say its only for preventative measure during winter seasons where there is a chance your TB can freeze. Answers my question, but I find it strange. I drove to work an hour ago and it was pretty cold (51*F) and I didn't have any idle issues, but when I was running a few days ago, when it was around (75*F ish) it was showing the same symptoms. Any ideas? Also I don't know if this will help, but my idle during hot temps is under the 3 last line on the tach.
