What is it called and how much does it cost?

I need to clean the intake and clean the throttle body, tighten cables, and change oil this week... any feedback doing all this?

 

I used the CRC brand intake cleaner. forgot the price but its cheap

 

It's about $2. Any Autozone/Pepboys should have it. Actually, any auto store should have something similiar. Watch out tho, you don't want to spray those strong chemicals on the throttle body butterfly valve...it comes with a special coating that can be removed if TB cleaner is used.

 

Which part is the butterfly valve? Is that the big circle in the middle? how do u avoid it? I was about to do this work using instructions from www.motorvate.ca, is that safe? I used to do it on my old car but never worried about spraying in the wrong spot before..
