Ruby, my husband knows lots of basics, I gather. He seems fairly knowledgeable. But the problem is it takes FOREVER for him to complete something. FOREVER. Unfortunately, this p1131 trouble code is a bit over his head I think. There are six possible "causes" according to the printout, and they are pretty involved/significant.
I will try the "ok, have at it" approach tonight and see what happens. I've let him go at it for a week now. Getting tired, lol.
