I am having intermittent engine performance problems, getting codes for sensors having voltages out of range, and getting a high voltage reading on my dashboard. Battery is at 12.6V with engine off and 14.8V at idle. Battery is 5 years old and looks to be spraying out some battery acid (dry white specs on other parts). Alternator passed twice at NAPA, failed once at Auto Zone, and passed twice at Advanced. Voltage starts at 15.1 is regulated to 14.6 and is 14.0 under load. I had thought bad voltage regulator, now I am wondering if an old battery can cause this.
Thanks for the help!
