Hi Wils, I can't wait to hear the answer to this one myself. If one side works then it's obviously the electronic and/or gasoline related items in the system that I have never had the pleasure of taking apart or re-doing yet are on the blink. My car runs great, but I know it is going to happen someday and just by the luck of the draw it happened to you first. It will be nice to understand exactly what it is that causes one side to stop and the other to go, how many variables to check. 2,3 4 or 5 items. I still don't know yet what the DK motors do? I'll be waiting to hear what you find out. I hope the guys come up with some immediate things to check and the way to do it and the tools needed etc. Thanks, Kurt
