S2k CEL - no code

I have the '06 dual-ecu kpro.

Lately when idling, sometimes (rare) it would drop to ~500rpm higher than normal idle, throw the solid check engine light and drop to regular idle.

When I plug in the KManager, hit datalog, no codes come up at all.

If I turn off the car and put the key on ACC, it would keep the check engine light for a bit, then blink 5 times, then turn off. (Not sure what that is).

Any ideas how to troubleshoot this?

I also noticed normal idle hunts just a very little bit but when the code gets thrown, it's 100% perfect.

I disabled emissions codes because I was getting
"P0453 Evaporative Emission Control System Pressure Sensor High Input"
Could this be related?

Only the OEM ECU is showing codes on the dash so you would have to use a scan tool to read the code. Since that ECU is not running the engine it does not sound like a serious issue.
