525ix idle problem
Hi Folks
My friend has a 1992 525ix auto , which idles strangley.
When in drive it idles at about 1300rpm, in neutral 2000rpm. Can anybody give any idea wat might cause this ?
Thanks
Rory.

Check for cracked or loose hoses under the intake manifold. everything that hooks into there can cause a vacuum leak if it is unplugged. If not, clean out that ICV
