1997 FJ80 1fz-fe starts and run if I stand on throttle but will not idle. (1 Viewer)

[Baroque]

I did a swap on my 80 because the original engine was shot and I decided to harvest a 1f. It start and if I hold the throttle open she runs great but stalls if I allow it to idle. Any help would be appreciated. can anyone provide me with an 1997 hood vacuum diagram? I just got done with the Noise filter on the Igniter ground circuit so I'm a bit beat.

Missing vacuum line?

I just noticed this today. It looks like there should be three vacuum lines here, no?

Just throwing it out there because my 91 did the exact same thing when the intake hose that connects to the air filter cracked. In my case it was a different engine but it would be easy to check on yours.

I was thinking similaly, That is why I was asking for the Hood vacuum diagram from a 1996.

Will the engine idle by itself when first started cold (high idle) but once the engine warms up and the idle comes down it then dies?

How far (rpms) do you have to push the throttle to keep it running, and when it's running (a warm engine) will it hold a steady rpm?
