Im having an issue with my fuel level being off by quite a bit

At full, it reads right at 3/4 of a tank. About 100 miles later, it reads on E, and 100 miles later its resting at its lowest position (right about where it sais premium fuel)

Initially I thought I had a fuel level sending unit problem, so I tested them following the FSM. I pulled the sending units out and tested them at full, and at empty, and both ohm out perfectly

I then began to do some research and have read that people have had some issues with needing to adjust the needle

Tonight I pulled the cluster out, and I also measured the fuel level sending units. I read 122ohms, which should be around 1/8 of a tank, or a little less.

I adjusted the needle to 1/8th of a tank, and put everything back together.

Upon turning the ignition back on, the needle moved itself back to its lowest resting position.

Is it possible the cluster is being faulty? I have noticed some akward behavior with the temp gauge as well. It will sometimes read normal temp when i just start the car up and its 30 degrees outside, and during the warmup process, if i step on the gas harder, the needle inches up, and when i let off the gas, the needle inches lower.

Thanks
