Based on the screen shot I'd say you have a wiring issue. Abnormal update rate, abnormal update rate, abnormal update rate, data erratic, abnormal update rate. Either a bad ground somewhere, a loose or damaged wire, tarnished fuses or maybe lost a terminating resistor? Probably start by pulling up the wiring diagram on quickserve and see if there's a common element with all those faults. Also easy to check the battery connections, wires, crimps and vehicle grounds before digging deeper.
