Recently I've noticed my GTI acting up. 2 separate problems. First, the car will sort of bog on very light throttle, then buck as boost starts coming on, feels like I have some sort of drag racing clutch. From the DV spacer I hear it letting off boost, and then just before it bucks back into boost, it sounds like it's sucking the air back in. Second, while rolling, if I rev to ~4500rpm, then let off the throttle with the clutch still in and let it go to idle, it will idle down to ~500rpm and come back up to normal idle, other times it drops under 500 and shuts off completely. Not a consistent thing either, as I've tried replicating it with no luck, it just idles down like normal. Any help?
