Is there any way to increase the idle RPMs on an '01 LX470? It currently idles at about 500, and there is a major vibration in the car. I searched the forums, and some people mentioned motor mounts, but those have been checked and are fine. I believe the TSB is 0010 (10006197), but don't know what it recommends. I would have to assume they would just increase the idle. Is this easy to do? Thanks.
