NC Throttle delay when pulling away

I picked up a 2011 NC 1.8 manual a couple of weeks ago and I’m experiencing around a second of delay on the throttle when bringing the clutch up.

The throttle response seems absolutely fine in neutral or once actually moving, it’s only when pulling away that the issue appears.

Plugged in the OBD reader and no codes are stored or showing, gave the MAF a quick clean and seen no improvement. I’ve also put in a full tank of Shell V-Power and some Redex to see if that made any difference but seems the same unfortunately.

Does anyone have any idea of what could be wrong or had a similar issue themselves? Cheers
