Get in car
Push brake and hold
Wait for flashing lights sequence
Write then down (3 blink, pause, 2 blink pause, 7 blink, LONG pause = 327.. then another one comes, and another... these are what is keeping light on

Could be LOW Oil
Low Water
Low Washer fluid
Low Pwr Steering Fluid
Worn Brakes
Low Trans Fluid
Low Diff Fluid
Air Bag Deployment Ckt
LIGHT out ;-)

Look for Jeep Err codes on ;-)

Signs of a bad valve cover gasket

My first question would be, what was the original trouble code that directed the mechanic to replace the sensors ? You seldom need more than one O2 sensor at a time. Its possible the exhaust manifold is leaking and that might cause a problem that would turn on the warning light. Or it could be something else.
A valve cover gasket will leak oil if it fails. No check engine light.

I just got an oil change less than 3 weeks ago and today my engine starts knocking and my oil light is on, could that be a bad O2 sensor?

No Bad o2 But Check oil Level. How old Was The oil That Came Out? Fresh oil Will Clean Out Sludge Deposits If The oil Was'nt Changed In A Timely Manor It could Have caused leaks. also Check Drain Plug Gasket for leaks And Make Sure Oil Filter Is Correct And Tight.

Harness or connectors (The sensor circuit is open or shorted). Rear heated oxygen sensor (Bank 1) may be faulty. The rear heated oxygen sensor (or sensor 2), after three way catalyst (manifold), monitors the oxygen level in the exhaust gas on each bank. Check your connections and make sure the right sensor is in the right location.

Both under constant throttle and acceleration I have had hesitation on three separate occasions over 3 week period the rest of the time it runs fine.

Check the front O2 sensor. I had a 99 Jeep that would stutter and seem to lose power while accelerating. No check engine light came on but took it to a shop and had them put it on a computer. Come to find out that the O2 sensor was giving the engine misreads and was telling the engine to take in more fuel. Causing one of the cylinders to misfire.

It is not true that you have to replace the O2 sensors when you replace the catalytic converter. It is suggested, but not required. Most exhaust shops can test the catalytic converter for flow. before you spend the money to replace a part that does not need it.

Will not idle

More likely something else is going on. If you had an O2 sensor issue, I would expect a check engine those codes and you will knwo where to go next...

When an O2 sensor fails, the system goes into a limp home mode, and esentially runs poorly, again look for error codes.

O2 sensor

Suggest you disconnect the Battery for 15 minutes., Negative Post. Reconnect and take a run out of about 25 miles of mixed Highway, to enable the ECM to REBOOT.

Engine light is on, car wont stay on

check the fuses , you can have a o2 sensor fuse open, also check the wiring because o2s are close to the cats or manifoldss some time they burn and get shorted.., other thing you can do is unplug the o2s and drive it like that and see if it shuts off , if it doesn't so the problem is around that sensor...hope this help..

02 sensor problem

Did your "check engine light" come on? If it did, then a mechanic would put a scope on your car's computer to read the malfunction code. The print out would indicate if the check engine light appeared because of a faulty O2 sensor. If you have a faulty O2 sensor it will need to be replaced since this it is the source of information for your car's computer with respect to fuel mixture.
