Sounds like a plugged oil pickup screen. Sludge will stop it up and cause oil pressure to drop when driving but come back up at idle.

Only problem is I had oil pressure till I changed everything out and now I have none!

Just need to know what to look at. Clogged screen is not an issue. We cleaned that.
