i was looking at the intake manifold chemical cleaning how-to and im a little lost. can this be done on a zetec, it says all vehicles but especially the v-6, but i dont really know what they mean about the vacuum tubes. the back of the throttle body has three of them, and i dont know which ones they are talking about. any help would be great!
btw i did search in multiple forums and couldnt find anything else...
