I seem to have a problem where my IAC didn't return to cranking steps on the second attempted engine start.
From the log
-Engine cranks OK. IAC cranking is 112 steps
-Engine exceeds cranking RPM (200 rpm) and IAC starts to taper correctly
-Engine stalls (reason is now fixed). IAC has tapered to 98 steps.
On the engine restart shortly after
-Engine cranks with IAC still at 98 steps from above then IAC quickly goes to its temperature based step count (56 steps) with engine still cranking
-Engine eventual runs with some TPS after an extended cranking duration. IAC is still at 56 steps
-Engine runs and IAC moves quickly to its temperature based cranking rpm (112 steps)
IAC tapers correctly and engine idles smoothly
Why wouldn't the IAC move back to its temperature base step count?
Running MS3 1.2.4 with a V3 board. Log and msq attached.
Many thanks

What if you upgrade to the latest stable release?
