That's a lot to read through. Your 6 Feb data for the fuel trim numbers seems rather high for the long term side. It also appears pretty erratic. However, the fuel trim numbers of today's data seem pretty reasonable and consistent. The last few frames though appear to be corrupted and should be thrown out.

Myabe instead of posting all the data, you could plot the fuel trim numbers from the data posted on the 6th and a separate plot for the data on the 10th to see how they compare. While none of the fuel trim numbers (I only scanned the data, didn't study it all) appeared outside of acceptable parameters, the highway data from today seems to be higher than typical.
