Rough idle / stuttering acceleration

[bruxism]

Hey guys,

I've recently bought a manual, 60 000km, 2010 Mk6 GTI. I noticed straight away that the acceleration had some stuttering in the low revs and also that it has been idling rough and popping occasionally on a cold start. When she settles under 1k rpm after a minute or so, seems fine. I've brought the car to VW to diagnose under dealer used car warranty and they've located a misfire and remedied the issue by cleaning and re-spacing the spark plugs. I feel as if the low rev acceleration in first has definitely improved, though other gears still don't feel as smooth or linear in acceleration.

Similar to Faint "miss" at idle?, but with the acceleration problem. Anyone ever had a similar issue or ideas on what else I could have them look for?

Cheers.

Do you know if they inspected the coil packs?

Could be related to oil consumption(fouling plugs) or a leaking injector. Out of those 2 however the cleaning/regapping plugs would only have fixed a fouled plug... Temporarily.

If you have a vagcom, take a drive a monitor MVBs 15 & 16 in the engine to see which cylinders are registering a misfire.
