Mazda MPV Engine Problems
Mazda MPV spluttering problem
Intermittent problems can be hard to diagnose, they never seem to happen when the mechanic is present to observe it. But when yours is misbehaving it continues to misbehave for some period of time. Next time take it straight to a mechanic and have them run their diagnostic equipment over it. It would be worth having the injectors cleaned, if they're partly blocked the engine can splutter and misfire, and have all of the engine sensors checked.
