On my '05 SLE I have 60psi at start up and then the gage moves between 25 and 35 psi. I thought it was suppose to hold steady at 40psi when warmed up? I do have fresh 5-30 and new filter in it. Any clues?
UPDATE: Took off the connector and put it back on,-now the O/P stays at 35-45-0 when at idle and warmed up!
