EST flag???
I just finished a datalog and noticed that the EST flag was checked throughout the whole ride. I have no SES light, just the flag in winaldl. Wondering if this would be causing me to run rich. Anyone know what would cause the flag?

have you checked the ignition timing lately?
if you have & didn't clear the codes, then code 42 will be stored.
