    Hi. I've noticed my 1.6 liter '06's engine shake and rattle more than usual at about 1400 and 2500 RPM. Cold weather will make the shakes more pronounced. The shakes might be less if I turn the engine off for a bit (like popping into a gas station to buy a coffee and come back) and turn it back...

    While replacing my spark plugs, I saw there is a hole between the 2nd and 3rd spark plugs and it probably takes a screw that is missing. (see pic below) The pic is taken after removing the second coil. But that hole in the metal is not the hole for the second spark plug. It is between the 2nd...

    Anyone experience this? Specifically with a 2011 3 GT Hatchback (2.5L) Car has 105k miles Basically, if the car is cold, it starts up fine but if I drive it a short distance, usually under a mile, turn it off for like 5-10 mins when I run into the store, it will sometimes struggle to start...

    My engine has been very occasionally jumping and stuttering, it feels like hitting a bump but horizontally, no codes are being thrown, no lights are showing. I know for a fact it's not bad gas but that's all I know. It could be a vacuum leak but I doubt it, it's most likely not to do with the...

    Hello everybody To begin with, I would like to tell you that i am a complete beginner on car-related stuff and I realize that my question may be stupid for which I apologize in advance. Two weeks ago I became the owner of a Mazda 3 2.0 120km, skyactive gasoline. At the beginning it was...

    Hi all, I'm attempting to use VRTune's Powergate 3+ to reflash my ECU. Unfortunately, when attempting to read the ECU for the first time, the Powergate spits out "An error occurred while reading data from ECU. Please try again." Any ideas? Thanks in advance, Bush

    FINALLY, I did another mod lol. This time a CS Engine Mount. I borrowed a pair of ramps from a friend and it was easy. The hardest part is the pop clips for the under tray lol. After I pulled the oem mount I applied some light pressure to it and I cannot believe how much flex is engineered...

    Hi All, Does anyone have any experience in replacing their engine/suspension mount? Amazon only has 1 listed on for our which seems odd considering it takes more then 1 mount to keep it steady. I wanted to replace all the rubber mounts since I've noticed at idle at a stop, especially with the...

    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...

    Hey there, I have a 2012 Mazda 3 skyactiv, the engine vibrates above 2000rpm and I can’t figure out why. It’s a 6speed manual. Just sitting with the parking brake up in neutral if you rev it up over 2000rpm you can feel a vibration starting. I’ve replaced all motor mounts and it’s still doing...
