I noticed that my jeep was running "extra warm"...lol....and tonight I noticed the gauge jumping a little, so I gave it a little tap and it jumped to the right spot...I think. Then I noticed my oil pressure was at 90+(maxed out on the gauge). Do both gauges run on the same part of wiring harness? Maybe both gauges are just old and not working correctly? Anybody else ever have this problem. The oil pressure usually reads about 75-80, but it was raining tonight on the way home so maybe that could have something to do with it too? I'm lost. Should I trace all my wires and make sure everything is nice and tight, or should I just buy autometer gauges and hook them up myself? BTW, this is a 1990 wrangler, 4cyl, 5spd. Thanks guys.
