Anyone who has experience tuning or working with 3800sc fiero swaps, can you give me a quick rundown of what all the sensor readings should be at idle? (My car is stock engine, 3.5" pulley, CAI, and 3" exhaust if that helps.)

I'm trying to diagnose a high idle issue and have no codes being thrown after a p0122 was fixed. I'm looking for values like MAP, MAF, O2 sensor, all the things you can read on a scanner at idle. I'm really hoping to narrow down the problem and get the car on the road.

Here's some of the typical scan data readings I see from a 3800 Series 2 SC at warm idle:

RPM: ~625
MAF: ~5 gm/sec
MAP: ~37kpa
IAC Position: ~20 counts
Spark Advance: ~25 deg
Calculated Cylinder Air Load: 0.15 g/cyl
STFT: 0% (+/- 7 is ok)
LTFT: 0% (+/- 7 is ok)
B1 O2 voltage: 0.100 - 0.900 volts (varies quickly)
Engine Cool Temp: 84 deg C / 183 deg F
Intake Air Temp: 17 deg C / 63 deg F
Injector Pulse Width ~2.5 ms

Hope this helps.
