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.
