Yup, it's dead easy and makes a massive difference!Pull the resonator box (if you still have it) off from on top of the throttle body (or just loosen it if you have small fingers!). You can then see the cables coming from the throttle valve. One of them (the one closest to the front, I think) has a button on it roughly where the cable goes over the valve cover (should be obvious). Next to the button there's a black bit sticking out along the cable, in the direction of the throttle body. Push the button down, and whilst holding it push the black sticky-out bit into the housing that it comes out of. Release the button, then press it again and still holding it open the throttle valve fully. The black bit should pull back out to the right position. Release the button and you're done.Hopefully that should make sense, but it's difficult to explain without pictures!
