Rehash of Bens original and photos I took today.
If your revs are eratic then you may want to try this out, it worked for me.
First loosen the two jubilee clips to disconnect a small section of the air pipe from the throttle body.
Then disconnect the plug from the Idle Control Unit.(ICU looks like a small cylinder bolted to the side of throttle body)
When this is done remove the two bolts that holds it to throttle body. The bottom one is difficult to access with a normal Allen key so i used a screw driver with detachable bits for this. Clamp mole grips to the handle of screwdriver if they are too tight to unscrew by hand. BECAREFULL NOT TO DROP THE SCREWS THOUGH.
The unit is now detached. Now undo the two screws on the unit its self so it splits in two.
Now spray lots of carb and throttle cleaner into the open holes. P.S. WD40 will only oil it carb cleaner will actually clean it out. Fill it up with this spray and then cover all the holes with your fingers and give it a good shake about. Tip left over spray out and see all the black crap come out. Repeat this last step over and over until the inside looks like new.
Now reassemble by reversing this guide.
