Do you have a rough idle condition? Any odd conditions when you change the oil?

Did you change both plugs and coils at the same time? Many people have had problems with aftermarket coil packs. Seems only the OEM Mazda coil packs work reliably.

And make sure they are NGK Laser Iridium plugs.

Dirty or clogged fuel injectors will also give you those codes. Try a few tanks with Techron fuel injector cleaner.
