My oil pressure drops when I stop raises a bit when I accelerate but never makes it past the quarter marker on the gage. Just recently changed the oil pressure sending unit cause my oil pressure was too high which fixed it now its running too low some tips or help please.

Dash gauges are notoriously inaccurate and are mainly good for you to notice when something is not normal, as has happened here. Have the actual pressure checked with a mechanical gauge, then if it is really too low, it is likely due to worn crankshaft bearings at the mileage you listed. They can be replaced before serious damage occurs to the crankshaft journals.
