Hi,
Please help me with this

I stored my 91 some years and i found that several sensor are not working properly , i replaced some.

I have scanner and i can read the values

Could some body please let me know how can i diagnose if the map values are correct ?

I don have leaks at intake, yesterday i have an error code map high, this is caused by leaks or faulty map
But car runs normal
I double check vacuum hoses and evrything is correct, i recently installed bigmouth intake and siamese runners and i replaced vacuum hoses.

Then i want to check the map sensor values

Thanks in advance

When you turn the key on engine not running the MAP sensor should be reading near 100 KPA. Then when you start the car and let it idle it should be reading near 40 KPA. It will move around with RPM and throttle position changes.

What about 7200 feet altitude ?
