Driving it off the cliff

[Stl-986]

Durametric doesnt do freeze frame unfortunately. Torque does but I haven't see it very useful but will get that info.

Does anyone know what the actual vacuum numbers should be or what the specs are? I have seen different numbers and can't seem to find them in the fsm. Can only see 25 psi at the brake booster in the fsm.

A general spec. is 18-22 in.hg at sea level.

Deduct 1 in.hg for every 1000' above sea level.
So if your in Denver at 5000' and your gauge reads 15 in.hg that would be 20 in.hg at sea level so you would be good.

But remember the most important part of the test is noting the needle action if any.
What I am really looking for is: is your valve timing ok.
