i searched a bit and couldn't find anything so here goes...92 XJ 4.0 HO auto tranny, just replaced the head gasket for the 2nd time, first time doing it i was stupid and screwed up, replaced it and its great now, everythings fine, except the temp gauge doesn't work. I replaced the temp sender unit the first time i did it, but it might have been damaged on the 2nd time. I checked the continuity on the wire and it has continutiy, and everytime i turn the ign. on the gauge goes all the way to hot and then goes back down. any ideas?
