my idle/stalling problem on the '87 300e is becoming intolerable. having adjusted the lambda tower and eha to no avail, i am at my wits end. i want to drive the car without electronic fuel injection, but i'm not sure what to pull or where to look. i know you can disconnect the whole system and run mechanical fuel injection, i just don't know where to start. where is the cis-e unit located and what plug(s) do i pull to achieve this? anything you could do to help would be very... helpful.
