Jeep has 57k mi. just had new fuel filter and radiator flush < 1000mi. Jeep started sputtering or missing while accelerating within past 100 miles. We had considerable rainfall in which I drove through some standing water. No check engine light comes on. Have no idea what could be the culprit. Can you help??

Engine misfires are most commonly cause buy the secondary ignition system. The fault may not be severe enough to turn on the check engine light now but I would suspect it won't be to much longer before the light comes on. Secondary ignition components which can fail include ignition coil or coils, spark plugs, and spark plug wires. A complete inspection of the secondary ignition may reveal the cause of your driveability concern. Also, codes may be stored in the engine control module even though the check engine light has not been on. Checking for fault codes and reviewing the data from the engine control module may also help in diagnosing your concern.
Thank you for your response. I will try as you say. I know Auto Zone will check your engine control module for free as some places charge up to $60 or more.
