1984 2.8 v6 won’t idle

[Tyler uppy]

I resolved a prior no spark issue on my ranger, and now it cranks and turns over just fine. However the engine will not idle and only runs for a couple seconds and high rpm before stalling. The truck will run if I get on the gas and I’m confused because this is the problem I was having before I rebuilt my carburetor. I’d like to know if anyone has knowledge of the vaccume system controlling this issue. I do have a couple vaccume lines that I don’t know where the go to. I will provide pictures and hopefully someone could tell me if any of them would prevent my truck from idling.

If your engine wiring is original(thinking it is since you still have the module on the distributor), the idle is controlled by the computer.

Your engine has a full blown EECIV computer system just a like a fuel injected mustang or other Ford vehicle. Your idle is controlled by a DC motor controlled by the computer.

How should I go about checking the see what I need to replace, any tests or telltale signs?

That open nipple on your 2nd picture your pointing at is a definite vacuum leak. Plug it off and see how it does.
