I've been having a strange problem with my gp for about a month now (I probably ignored it too long). At start up, my electric oil pressure gauge will do the normal sweep, and then peg at 0. Doesn't change if I rev it. After it gets warmed up the pressure will sometimes be 70 which is what it usually is or somewhere around 40. It will also randomly peg 0 or 100 while driving. I have a video of it staying around 40 cruising, then jumping to 70, and switching between those two , then going to like 3 psi, all while cruising. And sometimes if its at like 30 and I rev it to try to go up it just pegs 0 again. What is going on?
