So here’s the deal, as short as I can. One day, Jeep runs perfect. Next morning, start it up and my dash looks like Christmas. ETC, Traction Control, Check Engine and TPMS lights, all on. TPMS, easy fix. FYI - this is 2012 Jeep Wrangler JKU AUTO, w/ 84,000 miles, 2 1/2 lift, on 35x12.5x20 Maxxis...
