I'm not trying to start an oil thread on the early 2014 butterflies...as there are lots of posts about some that needed to be replaced. For the most part, my March 2014 Patrol has run rather flawlessly and has 7777Kms. I succumbed last November to getting the new off road map because I wanted to be able to kick start the rig. I noticed right away after getting the off road map in November 2015 that the RPMS at idle where higher. Still, the rig ran pretty well and in February I went on a thousand mile trip. No issues. This past week however, the RPMs at idle have gotten significantly higher, to the point where yesterday I was embarrassed sitting in the after school pick up line to get my stepdaughter. I kept wanting to let the clutch out a little to drop the RPMs and thought of just turning it off and making her come to me. So today I finally do something many of you have done years ago...which is to inspect the throttle body butterflies. The left butterfly was black from oil accumulation...and in comparison the right one looked rather shiny. I went ahead and ordered the Harmonizer (button was up today) and plan on going ahead and getting the new black butterflies and ports.
My question is....should I be alarmed at the oil accumulation on the left butterfly? I'm thinking not, and that the new plates and tuning will fix the issue. When I opened and closed the butterflies ...the left one seem to catch in a slightly open position position and I'm thinking that allowed for the discoloration.
The air filter is pretty clean after 2777kms...so I'm thinking there's not a lot of blow back.
