hey guys my 2016 rubicon 500 idles fine and revs completely fine in neutral but when i put it in gear and press the throttle too hard it begins to sputter. if i ease on the throttle to accelerate it wont sputter it will run normal but once given too much load it begins to sputter. if i am in thick mud, and go to give it any throttle it just begins to sputter as well. my first guess was clutches wearing out because its on 32.5” ol2’s but it doesnt seem that that would be the clutches. maybe fuel problem such as fuel pump?

Before I started thinking it's a mechanical issue I would try cleaning the fuel system with a dose of Sea Foam.
Walmart is the cheapest to purchase Sea Foam.
Put 1-2 ounces of Sea Foam per gallon of gas thats in the tank.

There was an issue with the O2 sensors on the early ones. (New Rubicons). Is there a code? Could also be the fuel or pump yes.
