AFR is not a fixed number, it depends on what the engine is doing. If it's idling cold, it will be richer than idling warm. Cruise is different from full throttle.

^ yea that is right.

On average though, even when warming up in the summer. We run rich to get the lube on, right? Or was the corrected with the ECU changes from Mazda. As a new owner, I still will NOT just turn on and turn off again with getting the car up to temp first.

Might want to get that check engine light looked at soon. You could be killing your engine.

14.6 at cruise is normal.
