You could have a bad oil pump. If you already replaced the sending unit and the problem still exists, I would consider changing your oil pump. When my oil pressure sending went bad, it caused my oil pressure guage to fluctuate wildly. I never got a check engine light.
It sounds like your looking at the problem as being a guage issue instead of an oil pump issue.
Just my personal thoughts.
It has a new oil pump, new sending unit, I've tried 2 sets of gauges and circuit boards so far, and it still isn't fixed. I found a possible bad connection on the plug for the cluster I'm gonna try to fix in a few minutes. Short of that it could either be the actual wiring, or a loose pickup tube. I used loc-tite on the threads of the pickup, and a punch to set it in place, but I guess it is possible it could move since it isn't welded. I'm messing with that connection plug right now, and I topped the truck off (it was a quart low of 10w30) with straight 50 weight. We'll see if that fixes it. I'll keep you posted.
