Question about 1997 Jeep Wrangler
Replaced cat and o2 sensor, only code that pop up is a power steering switch failure, even though I don't nave power steering? go figure.....
It is computer controlled and any attempt to adjust will get you no where. Check the entire engine intake system for vacuum leaks. Use a can of carburetor cleaner and carefully spry it all over the intake and hoses, if you hit a leak the engine idle will change. You can also do this with a bottle of propane gas. DO NOT GET CARB SPARY ON THE CARS PAINT.

Sounds good ninemil, I would also check for any bent or disconnected fuel lines that would restrict the fuel flow as well. I do not know if this has a fuel pump assembly but you should be able to hear it actuate on when the key is in the "on" position. How did it act before you shut it off? Was it harder to start? Make sure you buy a high quality pump (Carter) many of those cheaper brands will fail trust me.

Testimonial: "It actually had no spark or fuel . It was the computer. Thanks for answering"
Belt goes over power steering pump,under idler on left,over AC compressor,over alternator,over fan (with back of belt ) over crank pulley then over water pump (back of belt) then back to p/s pump. Routing is counterclockwise.

Something odd about what you posted. An engine that is running lean shouldn't be using a lot of fuel. Lean is when there isn't enough fuel going into the engine. Two other sensors that regulate fuel flow are the map sensor and throttle position sensor. Temp sensor generally would cause a rich condition but I'd test that too. Be sure to check for vacuum leaks at the manifold and lines as well as fittings... A vacuum leak will give the O2 sensor a lean reading...seeing that, the computer will try to compensate by adding fuel. Clearing codes can change the way it's running but as soon as the computer runs through it's internal diagnostics it will turn the light back on if there is a problem.
