Technical issue here... over the past week, my temperature gauge has spiked twice (to the very top). The warning light litup on the dash too... In both cases, I was pushing the jeep at high RPM... However, as soon as I let-off the gas and let it coast for around 10-15 second, the temperature went back to normal.
After the temperature went down, my RPM would only go upto 4K revs... until i pulled over and restarted the jeep... then everything went back to normal.
Coolant temp, oil temp and transmission temp were normal... has anyone encountered a similar situation? Any advice?

Thanks!

sounds like the computer said you where pushing it to hard which cause the over temp. i have read on the forums of sensors going bad and spiking. quick run to the dealer should beable to run a diagnostic on it and see whats going on as there was a code that was thrown when it over heats it should save in the system

Temp gauges aren't real direct indications, they are computer driven and will peg high when it tells them to. Sounds like something went wrong and it's trying to protect itself now.
