I haven't driven my car for two weeks. Now after warm up, my idle is not stable. It goes up and down 1100 rpm - 300 rpm. sometimes it stalls. My Chinese OBD II cable does not want to work, so I can't Vag-com it.
Anyone had this problem before?

Sounds like vacuum leak or fuel pressure just impulse response.

Or an idle stablization valve that is stuck??

Do you know where it is?

It's a 12 VDC pulsed item that has a parallel path with the main air flow that controls idle speed.

I would also search tyresmoke.net, I think there was similar problem there or here.<ul><li><a href="http://www.tyresmoke.net/ubbthreads/ubbthreads.php?Cat=">Search tyresmoke from this page, don't ask me why</a></li></ul>

Three nuts, if i remember correctly, hit it with some brake cleaner and wipe it down with a rag until all the build up is gone. That solved my stalling problem.

MAF? Stuck throttle cable?
