Hey, NOT all of the time but some times my engine would shake. I brought it up to the dealer and of course when they wanted to see the problem nothing happened. OK.. Well I told my mechanic friend about this and he gave me the easiest $7 dollar fix. He got me a 1 foot 4gauge ground wire and replaced the factory one that was probably an 8 gauge. Guess what, I haven't noticed the shaking again. So on with his theory about better grounding, I looked it up on the internet and I guess they have grounding kits for cars. The point there would be to run anywhere from 1 to 6 99% copper or higher to different points. I have not done this since I don't see a need for it.. but it's just an idea. Anyway, thicker Ground wire worked. Hope it helps you.

This is definitely a good lead mazda5lover. Thanks. So I brought this up with my friend thinking he might be able to provide me an explanation about how this is related to grounding (He's retired and restores cars for a hobby). He couldn't come up with anything definite though. So I just left it at that. I was wondering what your mechanic friend told you about his reasons for suspecting that it had something to do with the grounding. I surfed the internet for it and I only found stuff that links it to improved audio. Could you have found sites that would have offered better info? If so, I'd be very thankful if you can share me the links. Anyway, I'll bring this up again with the dealer. If they play dumb again, I'm changing to another one.

Well, my mechanic friend, who works for a custom repair shop tells me they do this to improve performance. Here is the information from the following website.
Track proven to add up to an additional 5HP when properly grounding engines. Helps prevent voltage drops and increases spark energy which eliminate power loss, thus improving overall engine performance of electrical components under extreme racing conditions. The grounding kit comes complete with; head to head, head to block grounding straps, battery to starter and battery to ground/block cables with the heat shrink sleeve tubing and all necessary mounting hardware.
How does it stop shaking I don't know... but the car feels better at idle. It starts up like a baby.

Our Mazda5 automatic has about 5000Km , yesterday I notice on the on-ramp merging lane as I was accelerating , I notice the car really hesitated at about 90 km/h , close to 3000 rpm. I tried flooring it , but the car won’t respond. Anybody experience this hesitation at about 3000 rpm. If this happens again …the dealer is going to hear from me. I heard from other Mazda forum that this is a common problem with 2.3 L .
