Yep... Varies by temp... when cold, full charge voltage from an alternator
is about 14.2VDC... when hot, 13.6VDC

Yep, and cause the PCM to calculate a longer PW for the Fuel Injectors...
Could saturate them and cause them to run static... less volume from the
pump with less voltage as well... could be bad for the engine.
