Hi 2004mazdatribute,
I would say it is more liley to do with the idling system. Either the cold start is not working correctly or the IAC is intermittently stuck.
If the Check Engine Light is indicating, get a scan done to retrieve for trouble codes and let me know what they are if any found.
If none, get the IAC and throttle body cleaned and retest.
