I forgot about the Klima tach reference. I'm now seriously wondering if the EDS is part of the reason I get rapid cycling of the compressor at very specific engine speeds.
For Example: Doing 70 MPH I run ~2800 RPM and the compressor will cycle on and off every 2 seconds or so. If I drop to ~2700 RPM, or speed up to ~2900 RPM, the cycling stops. With the bad caps I found last night, I have to wonder if the tach signal being sent out is noisy enough that the Klima is affected by it, but not the tach.
We'll see if new caps helps out any of these issues. I fully expect to find fault codes for the EGR system when I pull codes. The diaphragm in the EGR valve is bad, so I have vacuum disabled to the whole system. I don't intend to hook the EGR back up either, so let's not go there. Other than that, the engine controls are factory-stock.
Max - Interesting to hear of another person with the idle shake from the ELR/EDS. I did quite a bit of searching before posting this thread and didn't find anything from anyone else. Hopefully this thread has a happy resolution and helps someone else in the future. If not, my plan is to do exactly what you did - set the idle mechanically and forget about the ELR functionality.
