Do you feel ur Yaris shaking when waiting at red light?

[SunBug]

Just an update. I changed my spark plugs and filters. Only to suspect my transmission mount. Both the transmission mount and bottom motor mount were bad. Replaces those, and now the whole car just sounds rough. Im going to assume its the motor settling in. .. I love my car, but all this work is going to drive me nuts. I just hit 100k and have a feeling my Zippy is going to need alot more work. He still looks beautiful though.

I'm considering having my idle adjusted to stay at 600-700 rpm (after fully warmed up) to avoid the engine shaking. I'd rather burn slightly more gas than have it vibrate. This is an easy adjustment, right?

I have a 2010 Yaris (automatic) and my car shakes when my car is idol, in drive, with the brakes applied (at a red light). When driving its fine, and when in neutral or park its fine. But the minute I come to a red light the entire car begins to shaking. Does any one know what could be causing this?

It's normal I think, mine does it all the time

2007 AT (87K miles) with no shaking at idle in drive.

It's normal. My car idles at 550rpm when hot.... that is VERY low for a tiny 4banger to run smoothly so it runs a bit rough (it's actually impressive it runs at all at that rpm).
Cheers.

Actually re-reading it, yes. I missed the " with the brakes applied" part. Sounds like your brake booster may be leaking. See this post for more info:

^^Thanks for linking that, as I never would have figured out how to test that. Thanks.

Anyone know if I can raise the idle a little? I understand the vibration is normal and coming mostly from the low idle at red lights, etc....but I dont like it. I feel like raising the idle RPM's a little would alleviate the problem without causing harm.

The NZ is indeed a naturally vibey engine...in my Echo all the way up to today's Yaris. Just the way it is. Kinda un-Toyota-like, but the low idle is probably another attempt to keep fuel economy high. If so, it works.

I often shift to N (mine is an autotragic) or just turn the engine off at lights.

I have a 09 AT LB and I get a slight vibration in drive full stop while holding the breaks. I havent messed with it really to see if it goes away if I lightly let the breaks up some so Idk on that note lol. Its not a very bad shake, rather minor. I hear it shaking the front under carriage plastic molding on the under side of the motor where it meets the wheel well... *mine is slight messed up and a lil out of line* but I hear some of the plastic shaking more than I feel it shaking.
Ive had other cars do similar and after a quick spark plug change it stopped so I just assumed I might be due for new plugs. Im just about to hit 89k and I do believe they are the factory iridium's. I dont recall the previous owner ever changing them, and if they had I would be the first they would have called to do it for them lol. The slight vibration doesnt bother me much, just curious as to what was causing it, and like usual this site has answered another question for me. :D

It's more vibey than any four-cylinder I have driven, with the possible exception of the Chevy Aveo...a car which, BTW, was a big disappointment in so many ways, the interior looked so inviting in pictures! Of course my Echo is bad, it has 250k of some of the most poorly-maintained miles I have ever seen behind it, but also a series of 2010 Yarises or Yarii or whatever :D back when I worked rental cars. I also found that the Yaris' extra weight sapped all of the power and FE advantages I found in the Echo which made up for its un-Toyotalike lack of refinement.

Hello there,
I wana share the experience with Y-07 sedan.
1. Vibration during idling
2. More Vibration when AC is on
3. Vibration are common in all gear position P/N/D/3/2/L
4. Noisy vibration is entering the cabin...

I do solved these problem by replacing the Engine and transmission mount (total are 3 pieces ).. Now My Yaris-07 is nice to drive. no more vibration and noisy cabin ... .. I hope the tips will be useful.

09 MT LB Mine does sometines..
I dont believe this is 'normal', as some have stated theirs does NOT do it.
My experience is the same as XYaris'. Most noticeable after a freeway run when stopped at the offramp, in neutral, brake lights on. RPM does a little dance.. about 550 then dips to 450 for a sec or two, shakes, then back to 550, then back to 450.. up and down til I change something. Very annoying, feels like it's gonna die.. it would be fine if it would just hold 550 RPM.
I will be looking at the motor and trans mounts for possible wear/breakage.
If it were just an ECM flash, like some say, I would gladly give up the miniscule amout of fuel it would take to keep it running smooth..
I was thinking I might have some carbon buildup in the idle control valve (or whatever controls idle ???) and maybe I do.. Any tips on where/what controls the idle - and how to clean it???

I hate to bring up this old thread but was wondering if anybody has come up with a solution to this RPM Idle being too low and fluctuating up and down causing the motor to vibrating as if it's gonna stop? I think that motor vibration at Idle will cause wear & Tear on your engine Mounts.
