And remember CEL goes away on its own after around 8 starts of the engine, so that must've been around the eighth time you restarted it, so it went away (if the fault is found again, the CEL comes back on).

Things like misfires only trigger a CEL when the engine actually misfires, which usually happens during a certain RPM and engine load condition. When the CEL goes away it'll stay off until that condition is met again.
