Low oil pressure and light at idle. PLEASE HELP

Hey Folks,

So a few days ago I noticed that my oil pressure gauge in my 03' 350z was staying above 120 psi while driving. After doing some research on this site, I found out it was due to a bad oil pressure sending unit. So on Friday I replaced my sending unit, filter, and oil. It seemed to fix the problem, except now when fully warmed up, my oil pressure gauge reads maybe 2-3 psi (just a hair above the 0 line) and my low oil light comes on. If i give it a little rev the light turns off and gauge goes up, but when back at idle, the light comes back on. The pressure is also lower while driving then it was before all this started. My oil level is solid, motor sounds good, no oil leaks, etc. I stopped by my local Nissan dealer, and they want $180 bucks just to look at it. So here I am, hoping some of you may have some wisdom on why this may be happening. Any advice is appreciated!
