View Full Version : Jumpy Oil Pressure at Idle

06-23-2007, 10:00 AM
This morning, my 99 Maristar (310hp TBI) oil pressure at idle was "jumping" around in the 30-50 psi range - not just "floating" around. Once at 1500 rpms or more, the pressure stayed consistent (40psi at 1500 up to 60 psi at 3500).

I changed the oil since the last time out. Any thoughts?
