  1. Cylinder Deactivation

    2019+ Mazda 3 Discussion
    How does Mazda’s Cylinder Deactivation system differ from Honda’s? I’ve read about Mazda using oil pressure to control the operation of the system. How does Honda’s system work? Is Mazda’s implementation better and more reliable? I can only assume that Mazda’s system is a different design...
  2. Is it just me? (New engine ruins this amazing car)

    2019+ Mazda 3 Discussion
    I love this car so SO much (just like everyone else) but I had been having really noticeable gear changes in my lower gears like it feels underpowered or something. Took it into the dealer and test drove 2 mother 2019 3s (both a Mexico one and Japan one) they both had the same issue! Even the...

    2019+ Mazda 3 Discussion

    2014-2018 Mazda 3 Skyactiv Engine and Performance
    A project to upgrade the hydraulic transmission components on the BM 2014-'18 Mazda 3 6MT: Why? 1. I strongly dislike that Mazda has put plastic parts where I believe aluminum / steel should be used for strength, reliability and longevity. I want to replace it with a universal, easy to...

  7. Clutch issues from leaking brake master cylinder?

    2004-2009 Mazda3 Discussion
    Last week I noticed that shifting was getting more and more difficult, so as soon as I got home I checked the fluid level — sure enough it was extremely low. I check fluid levels weekly so a recent leak was my conclusion. On top of that, it seemed like the clutch pedal was beginning to feel a...
  8. #3 cylinder coil failure - 2015 sGT model

    2014-2018 Mazda 3 Skyactiv Engine and Performance
    Hi all -- Not my first post by a long shot -- I was PuMoDi until the board got hacked and people had to change their passwords. For some reason, mine was unchangeable (it was not sending the change to my registered email address) and when I notified administrators way back when I never heard...
  9. P0302, cylinder 2 misfire, keeps popping up

    2010-2013 Mazda 3 Engine and Performance
    I have a 2012 skyactiv. I'm getting this code which suggests a cylinder 2 misfire was detected. 95k miles. NGK Plugs have maybe 10k on them. I never got this code before doing the plug change, but now it comes and goes from time to time. I'm noticing no performance issues. If I clear the code...

    I know this may sound strange, but I would like to buy a BROKEN or SPARE clutch master cylinder from a 2014 -2016 mazda3 (preferably a manual sGT just to be sure it is the same part I will be replacing on my own car). I need it to take measurements so that I can replace the weak plastic OEM part...

  12. Sound of 4 cylinder engines

    2014-2018 Mazda 3 Skyactiv Engine and Performance
    Hey guys, First and foremost I'd like to point out what a lovely looking and handling car the Mazda 3 is. Loved it since I first saw the new design. The Kodo design language makes it look aggressive and tough. Sadly the sound that comes with the stock car is far from aggressive and tough. In...
  13. Misfire in Cylinder 4

    2010-13 Mazdaspeed 3 Engine and Performance
    So last night as I was driving on break, I was passing this car and in 4th gear blew past him (~85-90ish). After I did that and went to normal speed (~55pmh) I saw that my CEL came on. I had it looked at today at a local auto part store and it said that cylinder 4 misfire. I then talked to a...

    2010-2013 Mazda 3 Engine and Performance
    Long story shot, everyone here for sure knows by now that the second gen 3 has a finicky transmission. Some people report little to no issues, some people have had clutches "explode" etc. I've replaced my mounts all around, JBR 88a RMM, JBR 80a PMM, TRZ Transmission mount. I installed solid...

    Hey everyone, I'm wanting to make a pressure brake bleeder for my mazda 3 and have all the parts needed to make the pressure bleeder but have found that the mazda brake fluid reservoir cap costs something like 15-20 bucks which is a complete rip off if you ask me. Does anyone know of an...
