in the past people have reported longer cranks with seasonal fuel changes. Unplug the MAF and you will see a code, but often times a MAF that is for instance dirty will set no code but cause a lean condition .
I think there are posts on here where some can monitor fuel trim on open sid, MAF is the key input to calculation of fuel trim.
As I previously stated I try to clean mine on an annual basis.
