I have a manual 2006 subaru outback 2.5L XT that idles rough pretty much all the time and the rpm gauge fluctuates at stop lights between 500-1000rpm.

What was the problem with my Legacy Outback?
If it’s cold, it almost never exhibits this problem. We took it in with lots of fuel in it, and the problem started a few blocks down the road from the shop, with the same gas in it.

After explaining problem to mech he said it was either the fuel pressure regulator or the fuel filter, I took the opportunity to replace spark plugs, air filter, oil, oil filter, and a very dirty fuel filter (which I believe was the culprit in my case), and of course a very expensive O2 sensor. Car drives like new again…response is super!
