Ok so I started up Bonnie last night and gauges started acting crazy such is normal but this time where the actual mileage is 156000 the word error was in its place tried to take pic but it went away b 4 I could snap pic any thoughts I'm stumped

Could be a bad connection or some part going bad. I'd let it ride for the time being and then pull the cluster apart to reseat all the contacts (there'* a few) to try the easy/cheap way first.
