2004 Jeep WJ 4.7 oil pressure
Ok here is my problem. I have been getting a low oil pressure at idle, give a little gas it goes up to normal pressure then drops back down. I replaced the oil pressure sensor, and still get the same outcome. Oil and filter is all brand new 20 miles ago. Yes I was having this issue before the oil change as well. I went and got a manual Guage kit and put the Guage on. I am showing a good 10 psi at idle and about 40 of I Rev the motor. Other thing that is confusing is without the oil pressure sensor hooked up and the plug just hanging there I show about 40 psi on my dash. Shouldn't this show 0 with it not hooked up? I even took the oil pressure sensor and plugged it into the plug and just let it hang there not screwed into the engine and I still show 40 psi on the dash. Any ideas or ways to track the issue down?
Thank you

To much oil can cause loss of pressure, it causes oil to froth and aureate adding oxygen in the engine dropping oil pressure and HP.
Losing a quart can allow you to drive at higher RPMs while gaining horse's.
It could be a bunch of things but I've had this issue.
Did you install an Aftermarket oil pan or filters?
