Does it idle rough?
Thump/ clunk noise on start up?

It idle's rough but not thump noise on start up

If it has no fault codes coming up
Could possibly be a blocked line for the AVCS cam
The banjo bolts tend to break and go into the line
This is what happened to me
No fault codes very rough idle drove fine but when ever I came to a light the revs would drop and feel like its about to stall

Just a suggestion

The Sports light and Cruise control lights on the dash flash and a code says that the car is running lean, but when they test the car properly its not, that exactly what its like driving along it feels fine when I stop at lights the revs would either drop like its going to cut out or would set high like auto choke is on!!

As mentioned above AVCS solenoid issue probably.
gives a false code for one of the o2 sensors as it's not getting the expected signal, too much or too little cam advance causing incorrect AFR's
if they don;t know to look for this.. they shouldn;t be looking at it :assassin:

definitely sounds like AVCS issue. refer to this viewtopic.php?f=17&t=12451
keep in mind they are different models and could be different problems, this is just something for you to take into consideration.

Car is all fixed and running smooth as anything! In the end it was a loose howe which was causing a vacum, when the car was running at higher revs the pressure would pull the pipe into place at idle it would open up just enough to rough idle, all happy now and subaru only charged for the dignostic test

Phew!

Actually, don't be happy. Those pricks shouldn't be charging you for the tests. You said it has a warranty, if they don't know their product well enough, it shouldn't come out of your pocket.
I know this is the internets, but there have been umpteen posts in this thread by "amateur hacks" who would have found the problem in 10 min or so. To this I say fark the dealership, find a good subaru specialist and take your car there.
