You're running lean. A common problem in Mazdas is a delayed fuel pressure build up from the fuel pump. There's a service bulletin out on that condition. Do you experience a rough idle, stall, or hesitation?
REPAIR PROCEDURE
1. Reboot the IDS to clear memory before reprogramming.
2. Using IDS 51.9 or later software, reprogram the PCM to the latest calibration (refer to “Calibration Information” table) by following the “Module Reprogramming” procedure.
NOTE:
• Always update the IDS tool first, then follow on-screen instructions to download the needed calibration file for PCM reprogramming.
• It is not necessary to remove any fuses or relays during PCM reprogramming when the IDS screen prompts you to do so. You may accidentally stop power to one of the PCM terminals and cause the PCM to be blanked, or you may receive error messages during the IDS reprogramming procedure.

I had the same problem and it turned out to be a big vaccuum leak, Do you hear a whistle or similiar noise coming from under the hood anywhere? If so, check all of your hoses. Mine was behind the intake manifold..
