I've just done mine. What a pain! you need very small hands to remove the valve, as it's embedded inside the loop of the inlet manifold.. 1st unplug the electrical connection. Then pull off the two hoses, 1 at the opposite end to the electrical connection, the other underneath. Pull the valve from the bracket that the rubber mount attaches to, then pass the valve to the end of the manifold and pull out. Get some carb cleaner or other decoke stuff and spray liberally into the valve opening. If you have access to an airline then get some air through to clean any debris out. On refitting, a dab of grease to each rubber hose will assist as they are a tight push fit. Good luck. After I did mine the car didn't start properly, and when it did it sounded like it was misfiring. After a while it settled and now is fairly smooth, albeit at a lower idle. I'm going to change the plugs as I've found in the past that a slight hesitation when revving (which mine is doing now) is usually down to mucky plugs...
