Oil pressure gauge not sweeping when doing a gauge sweep test & runs above H or low L
So my oil pressure gauge has been doing some weird things...
what would cause my oil pressure gauge to not sweep back and forth like the other gauges when doing a gauge sweep (holding odometer then turning key and selecting gauge test)
The truck also runs with oil pressure immediately either above H or below L
Have already replace oil sender unit twice... seems like something is wrong with that gauge in the cluster? what could this be you guys think?
really freaking me out driving without knowing whether my oil pressure is really high or really low or just a bad gauge? how would you even replace this gauge? new cluster ?

please help!

My coolant gauge does the exact same thing. A gauge sweep has fixed it temporarily a few times but it keeps messing up. So it has to be the gauge itself or a bad ground.
I have the ECT (Engine Coolant Temp) reading showing on my Edge Programmer screen and it reads from ambient air temp on a cold engine to a few degrees under 200 while driving.
