#My Madza 5 gave me the uneven dling at the lights, then died whe I tried to take off. I took it in but am not sure what was done. It had to do with a computer?

Yeah, they re-flash the computer with a kind of software "update" which brings things like timing, advance, air fuel mixture, etc. back to tolerable levels. Stalling from a start is gone, but shake still there.

If you have an Auto Tranny with torque converter lock (Overdrive), you can experience this rough idle. A dragging power steering pump or other accessory can also contribute.

Hi I recently purchased a Mazda 5 and am noticing this same problem, When the engine is cold it vibrates periodically (sometimes the vibration feels like a thumping almost) when the car is stopped and idling. I'm curious as to whether this is actually a problem worth taking in to the dealer ? Since there are some veteran Mazda5 owners here, I would appreciate a little help here.
Thanks.

When I first bought mine last year I also noticed this iddle shake. I asked my buddy that works for Mazda as a tech and he told me that it was totally normal operation on these 2.3L Mazda engines because of some sort of intake shutter valve that acts sort of like a choke on the older vehicles. Mine also had a broken right motor mount that was replaced under warranty and it certainly helped a lot. It seems to be a known problem because there is a TSB

I would take it to the dealer, as any other car it has some bugs, but this is a brand new car so should not do that (I own an 06 and 08, and they see all 4 seasons, never had an issue when on idle)

there was also a fix that several had felt removed the idle shake and that was the beefing up of the main engine grounding wire.

Where is the engine's main grounding point???
 
The wire that is on the driver side inner fender structure is NOT the main grounding point for the engine, it is the grounding point for the battery.

Thanks for the input. I will take it in to the dealer and have them look at it. It will be due for its 3k oil change and service soon, so I'll hold out for another couple of weeks before taking it in. I'll also take this information about the engine mount and the grounding wire along because I guess I'm not totally sure how competent these folks are...
