Patience is wearing thin with it now!

I cannot find what's going on with my T5. It's idling all over the place and even if it settles, it's lumpy as hell and you can see all the lights dimming every time.
Press the clutch in to change gear and the revs rise by 300-400rpm instead of just holding steady, and on boost you can see the needle fluctuating.

Any ideas? Replaced the MAF, did a stage 0 not long back.

have you read the codes?

try unpluging the icv and drive the car for a couple of days like that, see if it settles down.

Sounds almost exactly like my recent problem... Throttle position sensor. Unplugged it and it drove better instantly.

Cheers for the ideas chaps, all taken into account.

We've now got an emissions light on, air leak?

Have you had the inlet mani off

No mate, it's been apart for a clutch and cambelt lately though. I was having the boost issue before the rev problem came in.
