Car has been idling a little rough, and some hesitation from idle. I was poking around the wiring when I found the KE controller connector was not latched all the way on. It took quite some pressure to click it completely in place. I only did this today, but the first drive it idles smoother with nice powerful takeoffs! Maybe a few of the pins were not making contact? This is also something worth checking if you have mysterious performance problems.
