you'll get a lot of answers as to what it should be.... mainly because there are many ways to do it.
pull your efi fuse, pull your spark plugs, and when cranking count the number of revolutions and match per cylinder. As you crank it over, keep the TB at WOT.
you should probably be in the ballpark of 140-160psi, I would guess..... how high the numbers show isn't as important as the variance between cylinders... you should see no more than a 10% variance (which can be quite the variance.... if one reads 160psi and another 144.... something is wrong)
to the OP: 4age's tend to get a bit oil consumy (not really a word, but whatever).... the 3 culprits are: small leaks, piston rings, valve stem seals....
#1 is easy.... inspect the motor closely for leaks... if you don't see drips on the ground that doesn't mean you're not leaking oil
#2 can't really do much except maybe add ATF prior to an oil change and run it for 15 minutes.... rings will either unstick or continue to have blowby.... other option here is a rebuild
#3 unless you have the special tools required to do an in-car valve job, it's gonna be a PITA... the head design doesn't allow for useful valve tools
I would say just run 10w40 and check it monthly or so until you decide to do a swap.
