I just changed the intke manifold and I tried starting it and it would not crank over. I found out the the distributar is out of timing so Ifixed that. I try and start it and it starts but goes to 3000 rpms and then just shuts off. I'm not sure what is wrong with it.

I checked all the hoses that I previously disconnected and nothing was undone.

Did you follow the torque sequence when you replaced the intake? You may have a leak there.

Yes I did. It is also making a high squealling noise when it gets to 3000 rpms.

Can you tell where the noise is coming from? Also, have you checked intake vacuum pressure?

You need a vacuum gauge to check the vacuum. I believe most parts stores will lend them to you. When you check it, vacuum should be around 18 to 19. All you do is plug a vacuum hose from the gauge to a vacuum port on the intake. As far as the noise, could it be a vacuum noise? I think that is the problem (but not 100% sure yet).
