So i've been chasing a no oil pressure issue (at least on my cluster) on my 95 lt1. This happened out of the blue one day as i stopped at a light. Since then, i've replaced the sending unit sensor, and today I changed the oil filter, and put in 10w40, hoping the thicker oil would make a difference. I also just happened to notice that if I bring the car up to 2k my speedo climbs up between 5-10mph kind going back and forth. Idk if maybe the cluster is going bad, and I have no issue at all with my oil pressure?

Also if I bring the car up to 2k i'm reading about 20psi. Another note, the engine doesnt tap or knock at all when cluster reads 0psi.
