... See some photos and notice the one with the red circle where the basis of the bracket just sits on the bottom and there is no bolt. Maybe they had to do this because they haven't used the spacers? Looks like they broke a bolt and didn't tell you about it (and probably other issues they had).

This means that during my driving, it collects data that are not important at that time to trigger a CEL but at the next start or even before the engine starts, the ECU must be using those info within the 1st minute of startup and at that time it will trigger the CEL. Afterwards, those data must not be significant since it will not trigger it again, even if I erase the codes.

There are many diagnostics which execute only at key-on. A good example (not specific to RX-8) is electronic throttle - most OEMs will implement a key-on diagnostic to test that the throttle can execute through full range of stepping. Generally these are diagnostics which cannot effectively run during normal operation, as they will affect the behavior of the car. My guess is that you are tripping an OEM specific, non-standard code for a key-on test and your OBD-II scanner is not reading the code properly.
