took it to mechanic for pressure check.Maybe gauge is not reading accurately
Don't remember exact # at idle, but he said gauge read about 1/2 of what it should be. When I rev rev up to 1000rpm pressure goes to normal.How low is it and at what rpms? Idle pressure? 2000 rpm pressure?
I've never seen a TJ oil pressure gauge that only said L or H. What year is your TJ?mine goes from L to H, also check engine light goes on.
I know the later ones (2003-2006) had the L to H oil pressure gauge, similar to the later year Jeep WJs. It was basically just a pressure switch that made the gauge stay vaguely in the middle of the range when there was good oil pressure. This was due to the many complaints about the "real" oil pressure gauges fluctuating back and forth. Even though the fluctuation is normal customers still complained. The earlier TJs like my 1998 and I believe 1997-2002 had an actual oil pressure gauge with 0-80 PSI.I've never seen a TJ oil pressure gauge that only said L or H. What year is your TJ?
