Assuming the 95 Passport has the same 3.2 v6 as the Trooper, it's pretty
normal for them to drop to almost zero at idle sometimes. I was concerned
about it, but have heard other folks say theirs does the same thing and has
for many many miles. I haven't paid much attention to pressure at 35/55,
etc, but always is within what seems to be an acceptable range.
