Back at it. Idle Keeps Hunting. 5.3, DBW, Mild Cam

[gcattani]

Evening,

Back at it!
- Engine start up Cold or Hot without issue
- AFR is near stoich with a wideband
- Engine is run on an engine stand

Issues:
- With RPM, Timing, and Spark Correction fixed (i.e. forced not to change), the DBW throttle body is hunting/cycling.
- With RPM fixed, the spark advance keeps adjusting forcing the engine rpm to cycle.
- throttle blips cause the engine's idle to hunt when dropping down, and typically stalls out after a few cycles.

I have looked through site, enlisted help online, watched vids, and read up, not to mention been changing parameters to suit, but no dice.

Some help and direction would be great!

Files:
- R2 was one of the first runs of the evening. You can see where the Idle and Spark are fixed, and the throttle body position % is hunting a % and down, cycling.
- R7 was where I was playing with the Adaptive idle parameters, and messing things up too much.

Thanks.

Ran the engine once again this afternoon.
- With locked idle at 950RPM and Timing/Advance, I narrowed in the Idle Airflow.
- Idle is still hunting!

What am I missing?
