Question about Jeep Wrangler
Unplug sensor cable from connector. Use 7/8" Oxygen Sensor socket, available at most auto supply and tool stores for around $10, to remove the sensor (It's a deep well with a slot cut up the side to clear the four wires that come out of the end of the sensor) . Insert new sensor using the same socket. The threads should have anti-seize compound already applied to them by the manufacturer. That is adequate. Plug the sensor connector into it's mate. That one is done. There are two Oxygen sensors on my '97 Wrangler. One is in the downpipe just after the connection to the exhaust manifold and the other is just after the catalytic converter. Easy to do!

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???

They are located on the exhaust after the converter, their is a special tool for this and some parts stores will loan it to you. Soak with a good penatrating spray as they practically weld on the pipe threads from the heat of use.
I like to use a torch to heat and use the contraction and expansion to loosen the threads.

There is a head temp sensor and intake air temp sensor, either of which could make the mixture too lean. Check them with an ohmmeter. Not sure the exact reading, but bad ones usually go 0 or infinite.
