My CEL was a faulty intake valve of some sort...some sort of cyclone valve...it causes turbulence and increases torque at low RPM or some such. They adjusted its position and are going to replace it when Mazda releases the improved version within the next month or so.
I also got my oil changed to Mobil1 full-synthetic at about 1,300 miles and got the tires rotated.
