The car listed above is a 300C with a 5.7L Hemi. Swapped engine, everything is back in, car running. Experiencing low idle and RPMs breakup over 2,000. Reading high voltage on o2 sensor heaters. Changed o2 sensors, still showing high voltage. Code disappeared, but assuming the high voltage problem still exists. At a complete loss right now, please help! P.S. Service manual says I need to perform a powertrain verification test.
