tremble and vibrate when stop at traffic light

[szyctom]

My x3 3.0, 2001, 65600 mileage.

Anyone knows what it is? when I stop at traffic light, car tremble and vibrate like getting a cold, but not heavily, more like a light shriver.

Plus: when car park and idle, sound like runing up and down, but RPM stable and constant.

your info and advice are greatly appreciated! Thank you!

Multiple causes: idle control valve
poor tuning
bad gas

Might want to take it to your mech and have it checked out.

Also, clogged injector, bad plug or coil, vacuum leak.

But when I had my car serviced, dealer did not say anything about it and now have 3 green bars left until next service.

I use Shell V-Power.

Any suggestion I can I do it myself?

Your inputs are greatly appreciated!

Try using Mobil premium. I seem to get a better performance from Mobil. I feel the same shiver only when on Shell V-power. I think they have to many cleaning agents in it... Not a big deal... Try the Mobil but if no help, go to your Indy shop...
