Also, I am posting a picture of my DME. Last year I struggled with a hunting idle which seemed to be caused by a broken resistor post at R306 (the eleveated resistor). I soldered the post back together, but am now wondering if this could be causing my rich issue. Maybe the resistor is defective. Looking at a picture of Chris M's board (dorkiphus.net) it appears that this resister may have even been replaced at some point, as it doesn't appear to match the others on the board. The thing I am confused by though is that this part of the circuit appears to be nothing more than a 12V to 5V LDO. I couldn't find the actual resistor but as you can see it does appear to be part of the (300) portion of the board.
Any thoughts?
