Yea- efficient, but is there any easier way to get to these passages (where are they and how do I get to them?) Can't I just spray throttle body cleaner onto the big hole that the EGR bolts to or will I catch my truck on fire!? I am just looking for any BTDT's for cleaning these passages on the 3.5L DOHC engine as I am not confident in removing the upper plenum. <img src="/forums/images/graemlins/scared.gif" alt="" />
