Jeep Wrangler Rubicon , Idles and Runs Rough P0302

Jeep Wrangler Rubicon , Idles and Runs Rough . This is a 2007 Jeep Wrangler Rubicon Unlimited. It was brought to me because it idled and ran very rough. It had a P0302 code set , and the plug wires are easy to get to so i checked for spark. No spark on number two cylinder coil pack terminal. Put a new coil pack on the jeep wrangler rubicon and the miss went away. Still idled high so i cleaned out the throttle body . The jeep wrangler Rubicon 3.8 seemed to run fine now. It has a electronic front sway bar that we will be looking into sometime soon.
