Remove these two screws with your T20 Torx bit and driver. Once the screws are removed, disconnect the harness and pull the throttle position Crank position sensors are known to go bad on the 3.6 and cause surging/power loss around 1.5-2k rpm. I would probably start there, since it's a cheap and easy swap. Consider it preventative maintenance if it doesn't fix your issue. 2012 Deep Cherry Red JKU Sport S - Tickastar, 6 speed, 3.73, Dual Tops. Save.
