#1 of 19 Mazda 5 idle shake
Jan 19, 2007 (2:36 pm)
Is a slight shake at idle normal for 2007 Mazda 5? I can feel it in park or in gear at stop light. Not sure whether to take it to the stealer. Also feel slight shimmy under my seat between 55 and 80 mph. Two wheel balances and it's still there. Everything else is great so I'm hesitant to make a stink.

I have had the same slight shake at idle. I spoke to the dealer and he had no idea. I just figure it is just poor electronics and injectors (just an fyi it goes away with 94 octane gas) and put it out of my mind. as for the shimmy there was a recall for selected cars regarding the engine mounts at about 55mph.

I'll try the 94 octane. Searched the threads and someone mentioned they replaced the ground wire to a heavier gauge and it fixed the problem. I'll give that a try this weekend and re-post. Engine mount recall? I'll have to look that one up. It may have much to do with the rough idle as well. Thanks for the post. It's kind of nice to hear "problems in common" so I don't feel like I'm going at it alone.

An ever so slight shake at idle only.
Can you describe the shimmy you refer to.
I'm not sure exactly what a shimmy is.

Basically the car shakes a bit between 50 and 80 mph. I called it a shimmy because it's not as if the steering wheel is shaking, but rather the entire vehicle under me. We have been driving a Toyota Highlander for two years which is smooth as silk at any speed. I would expect the same from Mazda.

Okay. I don't have the car shaking, perhaps
it could be a front end alignment issues though
that would appear as a vibration in the steering
I do have your first problem where the car idles non-smoothly sometimes.

Two times today it gave a nasty little jutter while first accelerating from a stop light. A quick blip of the pedal brought it right back - felt like it would have stalled though. Could the car be idling too low? Is it even adjustable? I would think it's computer controlled. Anyway, pissed but thrilled with the car at the same time.

"Searched the threads and someone mentioned they replaced the ground wire to a heavier gauge and it fixed the problem. I'll give that a try this weekend and re-post."
Did you try it?
I found that it idles perfectly smoothly in park but
in drive (with the brake on) there is a small shudder
every now and then. Your situation sounds worse.
