Engine I am having trouble with the engine in my 1991 Mustang.

yes. It is unclear why it was bent. The number 7 intake air was bent, so I replaced it. Is there a lack of oil pressure because it hasn't been moving for a long time? Fixed? Currently there is compression.

Ok so we noticed you replaced a lot of parts. Engine completely stock? You arent running a "chip" are you?
It's not a MAP sensor but a BAP sensor, but today I tried applying pressure with a hand vacuum tool.
It seems like I felt a slight change, but I don't know how much negative pressure to apply to find the correct answer.
Cars are very gas-rich.
I installed an air fuel ratio meter.
You didn't answer the question. Is there a vacuum source running to the BAP sensor on your Mass Air car?
BAP sensor.
Vacuum hose is not attached. There is a gray guard cap.
You can just see the MAF in the last video the OP posted. With that there should be no vacuum attached to the BAP sensor.
And just to be clear to the OP this is the BAP sensor

This is a mass air mustang...
Anyway im curious about this "has not been run in awhile" did you use fresh gas?
The gasoline is new. The unstable idle has been fixed. It emits black smoke. The gasoline runs out quickly, so I'm constantly adding new gasoline. I removed the O2 sensor and installed an air-fuel ratio meter, and the reading is rich.

This is a kit car. Is the ECU tag the part number?
