83 K10 Survivor, Part 2

[Wwes]

Kind of hit a couple potholes lately.
After sitting for a month, the old truck wouldn't start. After a couple minutes of cranking I just said "forget it".
A month after that, I went out and it started right up!

Last week it wouldn't start again. The next day started right up.

Took it for a short drive. Ran good, but did have a loping (searching idle). Pulled into driveway and it dies. Won't start. Luckily I'm at home.

Next day, go out and it starts up, then dies immediately. Ran battery down cranking.

Yesterday, go out, charge battery, it starts right up but has a real bad searching idle. Like it goes down, hits' the anti-stall, which doesn't catch it. Won't start again.

Going to test the IAC, TPS, and EGR. All the wires and vacuum lines look good.
