Question about 2003 Mazda MPV
The backfire is a result of excess fuel not firing in the engine. This could be a fouled plug or a bad coil pack. Basically the engine computer should be trying to compensate for this problem, so there should be a check engine light on. If no check engine light, then you would need to do a more in depth search. But I would start with a tune up.

check everything you can under the hood your air intake system all of it especially make sure all clamps are tight .. and make sure all vacuum hoses are good and not cracking or broken or just loose . you might run a little fuel cleaner through a tank of gas too cleaning the engine fuel system up some. just a few ideas..
