Anyway...your car is about to be old enough to not have to pass the emissions, so don't sweat it too much.

I've suggested this too (ONLY as a short-term fix) in the past, but none that I've heard actually did it.
OP - are TX emission limits changed to more stringent limits, based on ethanol blended fuel?
If the BLM is far removed from 128 (+) or (-), it will show that the car has been running out-of-tune for quite some time. Exactly what ELSE it will tell, as far as diagnostic procedure, I'm in the dark...
