Default Rough idle, Hatch specC

My hatch has just started missing a beat whilst idling, but it does`nt register on the rev counter. However, the boost gauge does flicker each time. The plugs have done less than 5000 miles. It drives well. Could it be a vacuum leak? The intercooler to throttle hose looks a bit perished, so others could be poor as well.
Thanks

If you vape or know anyone that does, blow some smoke into it to see if there are any leaks

Have a look what the avc's timing is doing, quad avc's does play up, especially if you have had a recent oil change.

I did change the oil about 600 miles ago; why does that occur?
Raggy, all good, but fuel reg wasnt plug and play, so didnt happen

Edit , There were problems with the banjo screens causing problems after oil changes esp on low rev & idle , sure motors could give you a better description of this scenario

So one screen looks easy, and the other could have been done when the cambelt was done the other day. Curse you Hindsight! Is there also a screen in the oil feed to the turbo, like the Legacy, and are they replaced or left out?
