I appreciate all the input. I also read in The Star magazine, that there is a chip that would actually inc. idle to 600+ instead of the 500+ of the original equip. setting. And it's an original MBZ replacement component. Murphy's law, I forgot what issue that was....
I f anyone out there knows what I'm talking about. I would great appreciate the info.
