Hi everyone, im new here so go easy on me. I have a 99 xj 4.0 auto that has developed a problem that I can not figure out. It starts and runs fine for about 10 minutes shows that it looses oil pressure and starts to flood and run very rough till it dies. It starts back immediately and runs fine with oil pressure for a couple minutes and does the same again. The jeep has no ob2 codes, and I have changed the pcm, oil pressure sending unit, compete tune up, and the bottom end has been rebuilt a month or two before the problem started with new oil pump. I am lost!! Its my winter driver and I need it fixed as soon as I can any help would be great.:repair:
