Hey Everybody I just traded my beat up rav 4 got an xb and I love it but I do have a question. I only have around 150 miles on it so far but I notice a slight vibration when I am stopped. This car is a manual and my idle is around 600-700 it is hard to tell on the Tach.
I did open the hood and noticed the airbox shaking allot. Is this normal? I have heard these small engines will vibrate more. I hope I am not just being to nitpicky and anal about a new car. I would have not even noticed the vibration but I was driving with the radio off that is how slight it is but it still annoys me.
Thanks for the help

I have an auto and sometimes when I stop I have this problem but I think it is just idleing too low because then it will correct itself and stop. My Dad is a Toyota service manager so I was going to ask him about it and see if I should turn up my idle a bit.

I think there's a TSB on this. Pretty sure because one of mine does it too.. gets down to like 500RPM and just feels icky. I looked it up, but haven't taken it in yet.

Is this something I should take my car back to the dealer for or maybe wait until I get some more miles on it? My rpm dose not really fluctuate on a stop . What should the idle rpm be normally? And I searched but can not find a copy of that tsb.

Thanks

my xa does this... sometimes with the window down i can hear the engine pretty loud, when at idle the tach will drop to 500- and the car will shake and feel like it's going to almost stall out then rises back up. noticed that it only happens with the air is blowing though, haven't had it happen yet without the air on. :roll:

Happens all the time on my xB too but havent had any problems at all, 3400 miles on the car. There are many other posts about this too and the problem is with the throttle cable where it connects to the throttle body. Apparantly just tightening it by a milimeter or 2 fixes the problem. I havent tried it yet tho.

reeeeeally.. interesting... i'll have to try that out. freakin toyota should do it though. :twisted:

this may be what you're looking for:

Make : TOYOTA
Model : SCION
Year : 2004
Service Bulletin Num : 01204
Date of Bulletin: MAY 20, 2004
NHTSA Item Number: 10007663
Component: ENGINE AND ENGINE COOLING:ENGINE
Summary:
INTERMITTENT ROUGH OR LOW ENGINE IDLE AT A STOP. *TT

so do i just give my dealership that service bulletin number and let them play with it?

Would that TSB affect 05's or just 04's

Thanks for the info
