'89 Sentra rough idling and dead battery problems

[ToxicWaters666]

Hey guys! I've got a 1989 Nissan Sentra, and up until the other day, I've been having rough idling problems, and it seems to be chugging along after a rough start-up. It also tends to stall when the gas is not constantly being revved, which then causes the battery to say it's dead when it is charged, and even when the battery is boosted, it barely runs. I've already: charged battery, changed/refiled oil, switched out fuel filter, switched all 4 spark plugs (old ones were very black and full of carbon), and inspected each cable. I've looked for vacuum leaks but was unable to find any. I'm suspecting it's an electrical problem. Has anyone had this problem, or how did you resolve it? all Fluid levels are topped up by the way

Sounds to me like a clogged IACV or a vacuum leak.
