Hi, let me start off introducing myself, im nick. Im buying a 2003 3.0 v6 from a buddy of mine for cheap. The only problem is when driving it it sometimes starts bucking out of know where and shuts off and wont start up for a while. It has no codes and nothing obvious wrong. Its had a tune up recently and my buddy brought it to ford and they keep telling him its the altanator, but the problem is intermittent so im confused. He also went and tested at autozone and they said its pulling 14 volts with the a/c on. So anyone with some advice on what I should start with please llet me know. I have a child due really soon so I don't have a bunch of cash to dump into it. Thanks gentleman for the help.
