What is this extra wire coming out of the AFM connector?
Troubleshooting codes 8 and 10 on a 1990 Miata, pulled off some electrical tape and found this:
Code 8: Airflow meter open or short circuit
Code 10: Intake air thermistor in airflow meter open or short circuit
Any clue? Is it the shielding for the signal wire? Would that cause the codes I'm getting?

You'll want to be taking off the plastic cover to the AFM with a sharp knife around the glue. I'm guessing you'll find a disconnected wire or rusted something.
Is that Ohio State or Oregon State?

I'm a bit apprehensive about fiddling with the AFM, as it's my DD, but it sounds like it might be the issue. Both codes point towards there being an issue with the AFM, which it wouldn't seem like that grounding wire would cause?
However, I'm only getting a small stumble off idle, and some uneven power up till 4k or so. I would think an AFM issue would cause bigger problems than that.

The only other thing I know of is the PO did an evaporative canister delete, because it was throwing a code for that. I haven't checked to make sure he did it properly, but I doubt it would be causing these issues anyway...
