2006 Mazda RX-8 — check-engine light turned itself off — still scan it?

I wouldn't throw parts yet. Loaded-suspension checks on the 2006 Mazda RX-8 catch play that a wheels-hanging inspection misses. If the cheap test changes it, stop and reassess. Run the total, not the monthly, before you commit. I've seen both outcomes, which is why I'd test instead of assume. This is the version I'd tell a friend.

I'd want a measurement, not a hunch. Capture voltage while the 2006 Mazda RX-8 is actually failing — after it restarts you've lost the clue. Save the big job until that test fails. Happy to compare notes if your setup is different. Not trying to scare you — just skip the expensive first guess. Cold start is when I can actually reproduce it.

Ask what changed right before it started. Get a real battery/charging test on the 2006 Mazda RX-8, not just resting voltage, before blaming a module. Don't erase codes until someone who can help has seen them. Happy to compare notes if your setup is different. If it repeats twice more I'll book time.

OP update: scanned the 2006 Mazda RX-8 again and still only have the one pending code, no new lights. I keep a notes app thread for this now.
