Shuddering when accelerating. ANY ideas??

[jrstevo]

Guys,

Recently had my Cupra remapped and the power increase was amazing, however since last sunday I have had occassional shuttering through the acceleration pedel as im accelerating hard. 

Anyone else experiencing this?

Im thining that I;ve either got a coil pack issue or plugs as its if there is delay like major turbo lag,

I appreciate that this is a GTI forum but im trying to piece others ppls experiences and rule them out!

Cheers

Jim

Find someone with a vcds cable and get your car scanned for fault codes in the first instance.

Very common mate.  Coil packs were revised (new ones endin F I think)
I had a massive drama trying to cure a miss fire on cyl 3 which was fixed by a new injector

Could possibly be the intake manifold flap motor (tumble flap) although agree with mike coils, sparks and VCDS first port of call. Had/have stuttering on mine (non tuned) gti and that was after new coil packs and sparks and new rev D diverter valve.

I reckon it'll be a cylinder 3 misfire, they're all the rage at the moment

LOL... Misfire will cause hesitation but i wouldn't have thought it would judder.

Could be the clutch?
