I read that it was possible to increase the idle speed by 50 RPMs or so on my 89 300sel by grounding pin # 10 on the idle speed controller.. Is that correct????? If so, where do I find the idle speed controller???

I would like to bump the idle up just slightly, but I understand that there is no oher way.. Is that correct???

Any help would be greatly appreciated..

Thanks,
Jay
