Im getting a low input voltage and a high input voltage code thrown.its getting its 5.13 power supply, sitting at .8 and has no dead or flat spots when opened.also getting a misfire on cylinder 2 and a rough idle.i have been chasing a similar problem for a while now and got a new battery the other day.this seemed to help it but im getting 13.8 exactly out of the alternator.maybe its on its way out and is supplying just enough juice to keep it running but jacking with eletronics?
