I have been lurking in this group for awhile, but no posting yet. I don't know enough to contribute. I purchased my 1980 450Sl in fair-good condition in the fall. I have not been able to get to it until recently. I wanted to strip the interior (seats and floor insulation) to give it a good detailing and inspection. After I removed those things and NOTHING under the hood, the throttle linkage will not return to idle unless I pull the gas pedal back by hand. I looked under the dash and can't find any thing that would affect the linkage.
Any help will be greatly apperciated.
