99 xj 4.0 we went wheeling last weekend and a couple hours through the trail the check engine light came on and then the temp gauge started going from 210 all the way the the red then back to 210 then to 100 back and fourth pauseing randomly. the jeep was running fine, not hot at all. i tried changing the sensor and it didn't change anything anyone ran into this. any ideas. its still doing it
