My car did this aexact same thing, I cleaned the throttle body out (wasn;t even that dirty) and it fixed my problem... the first time I got the code p0340 was over a month ago... my alternator is still running strong... Check the throttle body first... thats a free fix... then go with alternator. I'm waiting for mine to die now that I jinxed myself...
