We were planning on going on a Route 66 trip this fall with the MBCA group. George Murphy, tech director for the club, emailed me a list of things that I need to do to my 26 year old 450sl to get her up to speed so that we don't get stranded in the Mojave. One of the spares that was recommended that I bring with me is an Idle control module. I have searched this forum and several parts sites and have drawn a blank on what it looks like or where it might be hiding. Can anyone help? Do I really need one of these?
Appreciate your help!
