Engine excessive vibration

I experienced an excessive vibration issue with my 2012 rubicon last night. It started when the rubi was stopped at a light with gear in drive. The vibration sounded like the ones come from low rpm. I shifted to 'N' hoping that it goes away but vibration remained the same. I shifted to 'P' and vibration remained also the same. I shut the engine, restarted and same story. The thing is it happens on and off (exactly every other time) . I realized that it happened after I refilled with gas (I was thinking maybe it is dirty gas - FYI - I filled from Shell). One thing I did when engine was vibrating, I shifted to 'N' and applied gas so vibration went away.also, no vibration is experienced while rubi is actually moving. Please advise if you have experienced similar issue. Thanks

Same thing with 2012 Sport. Intermittent. Going to get it checked out at next service under warranty.

Your RPM's dropping low?

Warranty time. We just had a 12 with a faulty fuel pump. Also PCM issues and shorts causing engine miss fires.
