Just replaced all Vacuum lines with quality scilicone tubes.

Mr.5 did it at my mileage due to a code he threw. Mine where dry and brittle, and some cracked in your hands real easily. The oem stuff is garbage, and is real leaky. Very noticeable improvement in the responsiveness, and performance. Mr.5 had diagrams of all the tubes, posted on his thread. You will need 11ft.
