Very simple to do.
Locate the Allen bolt adjuster on the top of the throttle body.
Get the car warm then whilst on tickover clamp the hose on the right that goes from the throttle body to the plenium chamber.
At this stage the car might cut out, like mine barely idle, or if it sits nicely at 600rpm it’s ok.
If you need to adjust make sure you have a pen and paper to note your adjustments so that if it all goes wrong you can return to original setting.
I used a T handle Allen so I could accurately measure half turns which to open the air screw is anti-clockwise. Mine was three half turns.
Apparently you need to watch for the fan kicking in as this affects the rpm when you are trying to set it.
Hope that makes sense.
