Was told to check the fuel pressure regulator for leaks into the vacume line. Pulled vacume off and it crumbled. Replaced all the vacume lines except for the one that goes to the interior. Ran better for a while. Then started running rough again. I have a digital battery charger with an altornator tester function. Put that on and the alt was running at 62% output at idle and 75% at above idle. I charged the battery to 100% and it runs fine. Will see what happens after battery runs down again. I think this lack of voltage is my problem. Any ideas. Thanks in advance.
