    2004-2009 Mazda3 Discussion
    I have an 05 hatch. Non turbo 3. While accelerating, the car very violently jerky back and forth. More in the lower gears. I'm afraid to even drive it because I don't want to do any damage. It feels serious Brand new spark plugs. Coil packs are good. I'm not showing any codes
