Plain Jane OEM nothing to see here rebuild

I stepped away from the car out of frustration. Before I did that I tested the thermosensor at the ecu for both resistance and voltage. I couldn't test the lowest temp what with it being summer but the other temps checked out fine.

That same day I checked TPS and it's still good and at 1v. Took it for a drive and it seemed better idling but afr are still 10.8 at idle. Then between stops it developed worse idle and hot start issues. It did it 3 times and that's when I parked it for a week or so.

IIRC the IAT tested fine at the ECU. I'll look at my notes and also test it again, this time at the sensor.

I guess next up is to test AFM/MAF. One thing to note, I have a Cosmo AFM/MAF for a 13B. I'm assuming that could be a factor in the rich idle?

I have a spare set of coils to swap on in hopes of a magic bullet.
