I have a 2012 Expedition XLT 5.4L 176K miles. I have been using an old phone as an auxiliary dashboard for a few years that is synced with my Bluetooth ODBII reader. Comes in handy.
I'm getting a knock count of 1 while driving around and it'll go up to 2 when under load, then settle back down to 1. The count is 0 at idle or when I am coasting on the expressway. It's not throwing any trouble codes for the knock count.
Any thoughts on what I need to check in order to get this addressed? I'm not detecting any other performance issues. I am getting stuck lean codes from both of my downstream O2 sensors on both banks. I'm changing those sensors next week and installing defoulers.
The plugs, wires and coil packs were replaced about 50K miles ago as well.
If anyone has any advice that would be very welcome. Thank you.
