Regarding my issue with my 2014 Rubicon and #3 Cylinder misfire. It ended up being a broken spark plug installed at the factory.... It's been a champ ever since (10.0000 miles) In fact, I put a Super Chips tune on the motor setting it on performance 93 octane, since I only use premium, and it seems MUCH happier. Made a dramatic difference with gas mileage too. I wouldn't believe it unless I experienced it personally but these Super Chips box's do what they say...... So far so good!!!
