Lack of power when moving off

[Clio90]

Just went out in the car tonight and when i tried to move off the car acted like it was going to stall and there was no power, put my foot down to give it more revs then a second later i got all power back. Any ideas what this could be?

Gunked up throttle body maybe, give it a bit of WD40 and a wipe.
