<B>Tools Needed:</B></p>
<ul>
<li>Medium Sized Philips head Screwdriver</li>
<li>10 mm ring spanner</li>
<li>13 mm ring spanner and open ended spanner </li>
<li>Pointed Nosed Pliers</li>
<li>Scraper</li>
<li>Ball hammer (If making your own gasket) <BR>
</li>
</ul>
<B>Other Material/s Needed:</B></p>
<ul>
<li>Gasket or manila so you can make your own</li>
<li>Grease
</li>
</ul>
If you've got crappy idle like just about every other VN owner which is not uncommon out there here's a quick and simple way of making things a little better or noticeably better.

<li>Using the Philips head screwdriver loosen the clamps on either end of the intake and remove to a safe place which won't get in your way. The throttle body looks like <a href="http://www.justcommodores.com.au/images/Throttle_Body.jpg" target="_blank">this</a> <br>
If you have cruise control remove the 2x 10mm bolts and retaining clip on top of the throttle body. </li>
<li>Remove the Vac and Purge hoses from the throttle body and place them aside.</li>
<li>Remove the accelerator cable, I find it best if you spin it so the throttle is open as this makes life much easier.</li>
<li>Using the 13mm ring spanner and 13mm open ended spanner remove the 2x 13mm bolts holding the throttle body.</li>
<li>Remove both wiring connectors plus the PCV valve connector going to the throttle body and while your at it the MAP sensor tube running to the rear of the throttle.</li>
<li>The throttle body should now slide out allowing you to have easy access to it. <br>
If you are going to leave the area open for an extended amount of time just place some clean rag in there to prevent any rubbish getting inside. </li>
<li>Place the throttle body on some clean rag and remove the 2x Phillips head screws using the Philips head screwdriver holding the IAC in place.</li>
<li>Using a gentle rocking motion remove the IAC. A picture of the IAC fresh from the throttle body without being cleaned of course can be found <a href="http://www.justcommodores.com.au/images/IAC_Dirty.jpg" target="_blank">here</a>. </li>
<li>You'll notice a lot of carbon and deposits on the above picture, using some petrol or carby cleaner in a well ventilated area wipe over the pintle itself, in the end it should look something like <a href="http://www.justcommodores.com.au/images/IAC_Clean.jpg" target="_blank">here.</a></li>
<li>Just before placing it back on to the throttle body just check to make sure you have enough grease on the o-ring and check for any damage, if damaged simply replace it.</li>
<li>Prior to placing the throttle body back on to the vehicle ensure both mating surfaces are clean.</li>
<li>I make my own gaskets within reason as I wasn't able to buy one, this can easily be done using a manila folder and a ball hammer. Place the manila folder over the throttle body and gently hit it until you have the perfect gasket which is much better than a bought one
</li>
<li>From here simply do everything in reverse. </li>
