 Subject: Vaccuum?

Just one quick question what should the vaccuum reading be at idle I checked mine the other day and it was at 17 when at idle and then when you stomp on the gas while driving it drops to pretty much zero.

Direct from the Haynes Repair Manual for 1997-1999.
(I'm assuming you've got it hooked up right and the engine is warmed up)
6) Read the vacuum gauge; an average healthy engine should normally produce about 17 to 22 inches of vacuum with a fairly steady needle.
It then goes on to list a bunch of things that different readings mean and what to check. If your steady at 17 though, with a warm engine at idle, plugged into the intake manifold vacuum and not the throttle body vacuum, your fine. :0)

Thanks the haynes manual I have doesn't mention anything about vaccuum just that the hoses should be inspected from time to time. I checked it at the brake booster just because of the ease of access, would it change the reading if I checked it from the intake?

It might, I imagine it might be a little lower at the Brake Booster than it actually is.
