idle speed control minor problem

[rares]

Nope.... Problem still there. So in order to keep the idle speed up , where it should b, I drive in sport mode in town ( a lot of stops and go) and normal on highway. Now that the summer in here , The AC on helps also to keep the rev up . I just don't want to replace the transfer case again.

I don't think driving it in sport mode or having the AC running will cause your transfer case to go boom! not changing the fluid and/or guibo's will cause that... or the +140mph runs on the expressway

I would think you have some kind of vacuum leak or leak in pipe between your MAF and intake. My N62 with the AC off will have a rough idle at times too, I think it's because of the weather ( or at least that's what I tell myself )

Hope you find it!
