I checked my codes today (like I do every so often) and I believe I got a code 11... "momentary loss of power to ECU"...can someone better explain this to me? And could it be caused by my battery's ground wire being loose? (I wiggled it a couple of days ago, and now this code)

edit: i was just thinking about it and when i was installing the CPS about 3 weeks ago the wiring was all screwed up, and i ended up cranking the car so much trying to get it to start, that the battery became depleted, and it would crank really slowly, until the starter would just click...i let the car sit for about twenty minutes after that and I was able to get it to start...could that have caused it?

That old engine harness has caused problems from the beginning, you really should change it out asap.

Yep, I know :(. I am hoping to find a used one in working condition to get me by for the time being. My car runs fine though, I just happened to check my codes and that popped up, I just need to tighten the negative lead on the battery i guess.
