It’s definitely the cruise control. That little arm is very restrictive. TBD if lubing will help it to return.

The idle like that is consistent with the 3.5L OM603 in my w126 when the EDS is disconnected… I need to check for clean connections. I do have a code reader box coming….

Cruise worked once when I tried it. May try to lube it up but won’t hold my breath. I wonder if the linkages can be reinstalled without removing the intake??
