Hi I have a 1992 wrangler yj and the oil pressure gauge works but some times it goes crazy and goes all the way one way and another then works again I have no clue what it is another problem i have is with the temperature gauge, when i turn the jeep on the needle goes to 100 degrees but no further i replaced the temp sensor in the thermostat housing does anyone els know what i can do.

you changed the wrong thing. what you might want to change is the tempeture sending unit which is located drivers side on the head near the fire wall. the item you changed is to give information to the computor on engine temp.
