After you reset the AFM plate height, how did you recalibrate the mixture? If you unplug the OVP does idle still surge?
I noticed that you have a 3.0 in your 190e. Did you swap out the ECU, AFM, FD too?
I like the way Steve Brotherton sets the initial mixture. With the EHA unplugged , you read the voltage of the signal wire of the O2 sensor @80C. You want to see the voltage oscillating around .45vdc. This is the range that the ECU -EHA can react and achieve lambda. You then of course, plug the EHA back in.
