Here is the tune file used to make the log. When coming to a stop, it surges a bit and drops idle down, but doesn't die. It also still hangs in park if I rev it. So I imagine they are related to the same airflow issue.
Any suggestions?
Btw, this is my wideband cfg, but it wasn't hooked up. So it just shows a flat AFR across the board.
