I have 99 4.0L jeep wrangler with 105,000 miles. Runs like a champ. today i noticed my oil pressure guage is pegged at 80PSI. it does not move @ idil ,city or highway changes . checked the oil level is fine absolutly no leaks. the other guages work fine. and the engine temperature guage reads normal. Any ideas? mike
update i fixed the problem there is a test built into chrysler products to test the guages and a very simple fix for the high pressure as long as you dont have any motor problems which you will know if you do. im me and i can help
