I have 2000 4.0L jeep wrangler with 150,000 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?
