'93 XJ - Oil Pressure Gauge Pegs
This is a bit odd and kinda opposite the way oil pressure gauges and/or sending units goof up but mine reads off the scale while underway. After warmed up it will read about 20 psi at idle and will peg out as soon as you come off idle.
1.) Is this a common issue w/XJ's?
2.) My first thought is to replace the sending unit.
*No, I haven't connected a mechanical gauge to it.....yet.
Really I'm wondering if there are issues with the OEM gauges.
