Mazda Repair: Quick Question, fuel filter, fuel injector

Question
Hello,
     I have a Mazda B2500 pick-up. It is starting to kind of chug along, sputter. I was curious if you may have an idea what this is? Regards, Skyler

Answer
more then likely caused by a faulty fuel system or ignition system. try replacing the fuel filter and running some fuel injector clearer if that doesn't help you'll have to look deeper. i always start with the small things first and seeing as most people never replace the fuel filter it's a safe better and should be done anyways
