Got two new (Bosch) upstream O2 sensors to have installed this Thursday for the PCV re-route job. I figured that after 127K miles that its time that they be replaced for this groove mod.
Thanks to Tracy G for his superb work, I will be having fun this month and this spring saving and reporting good MPG's and awesome power gains.
In another few weeks or so, I plan to start on the RVS Technology for both of my vehicles.
Fun stuff, lots to learn, and a great way to start the new year in Alaska!
