Simply, readings aren't 100% kosher: IAT is reading 20°F high, MAF is idle 2.3-2.5 which is quite high. I know the BCM *learns* the sensor and translates it to performance but those are notabley off numbers.
What has me looking at the MAF? Idling during warm up is rough, dog rough, and if driving through warm-up prone to stalling when RPMs are low.
Some of us early 2nd gen'ers might remember the MAF issue and updates from back in the day, well it's just like that... hot/humid air messing with the PCM during warm-up.
The MAF doesn't look dirty. And with only 80k on it, babied with regular OEM grade intake filters, but it is original and 17 years old.
So, cost of a new sensor versus faffing about with cleaning this one. What's the hive-mind think?
(If the MAF/IAT isn't the issue, the shade low MAP number has me suspecting throttle.)

Now the temperature is reading 15°F *more* accurate and the idling RPMs are settled down, not jumping around as they had been doing. Driving the car, it's more responsive.. so seems that's all it was, dirty MAF sensor. A few days driving around will prove it's been resolved.
