My 95 had a low reading from the day I bought it about three years ago.
I checked the sending unit and the top part of the unit fell off in my hand when I reached down to check the connection.
I'm surprised it was still working as lose as it was from the base of the unit. It would read a little low, cold but never reached correct pressure when warm.
I changed the sending unit and now it works great, much to my relief.
