Question about Jeep Wrangler
Assuming the t-stat is good, I'd look at the wiring next. Make sure the connector is clipped onto the water temp sensor/back of the gauge and that the wiring is not chaffed, etc. If that all looks good, replace the coolant temp sensor...they're $20 or so. If it still does it, the gauge is bad.
