I had a similiar problem it turned out be the catalytic converter. I believe there was a recall for this problem.

SOURCE: How do I replace the interior LH door handle 97 Jeep Wrangler?

you will need a t-20 or t-15 torx bit driver to remove 2 screws holding the handle this is all that holds them on, on once you have a replacement handle it is easier to remove 2 lower screws on the door panel and unsnap the door panel to loosen it this will allow space making it easier to reinstall new handle just slide each end into the slot and reinsert 2 screws to not fully tighten until door panel is snapped back in. the panel is held on with clips and can be released using plastic pry tool around door panel edges.

how long has this been happing..one tank of fuel or more, could have been bad gas, replace filter,, put gas dryier in fuel tank..if it continues could possibly be transmission related..the reving down doesn't sound like transmission though if tansmission was slipping it would rev up..good luck

SOURCE: Oil pan removal on a 97 jeep wrangler

Instructions can be found in any basic manual but the simple version is to remove anything obvious that will be in your way (starter, trans lines etc). Disconnect both engine mounts and raise engine to get better clearance (watch stuff on top so you don't break anything) I usually stuff a couple of 2x4 wood blocks between engine & mounts to support it. Remove all pan bolts and take it down (remember pump pickup will interfere) Do what you need to do, then reverse process.

The check gauges light is normal because at 400 rpm it isn't running fast enough to build sufficient oil pressure. I am guessing maybe a vaccum leak???
