My 2012 RV-12 EAB has about 400 hours and now has erratic oil temperatures after about a half hour in the air, not always, but when it happens it is bothersome. It goes back and forth down to under 120 so the 180 panel shows problems. I carefully looked at the sensor(nothing obvious), the sensor to wire connection, now it's wire tracing time. Anyone have experience with this syndrome, and advice before I check further? Mark
