on my 97 stratus the oil gauge keeps shaking kinda like the one on those late 70's chevy half tons. do you know why it does it it never did that before. *note i am useing a 1997 jeep charokee cluster i like the full gauge cluster

that could be a very good reason why your gauge fluctuates is because you're using the wrong cluster for that car. I'm surprised you haven't had communication problems or your cluster not working at all.
