Default Engine revving on its own!!

I've just replaced my oil cooler after a major leak an also found a fuel hose split the car is revving high on its own. Took it out for a test drive an when I put my foot down as I come off its still boosting for a second on its own!! Scared the **** out of me.
When it's stationary if I quickly stab the accelerator it will rev right up on its own!
Any ideas? Cheers.

check the actuator is not sticking or needing adjusting, Had a week actuator on my Evo and it done the same held boost for a few seconds when lifting super scary.

Cable sticking? Or throttle body/butterfly needs cleaning?
Makes sure cable is sat right and not trapped,spray some wd40 etc on the cable,clean throttle body and spray some stuff on that too.
