Sticky throttle

[Infident]

Hello guys

So I have a 2007 berlingo with a problem of a sticky throttle, when I let go of the gas to switch gears the revs stay up (or increase if I'm accelerating hard) for a second or two, it doesn't stay on forever, just for a moment but it's racking up my mileage.

Any advice on where I should look or what should I do?

I had same problem with my 08 petrol berlingo If your clutch cable isn't running smooth it does what you describe,If the clutch pedal is squeeky or stiff try looking there.
