Question

P0350 Hyundai - Sonata 2003 2.4L where is the primary ignition coil located / facing the motor - is it located on the right or the left?

Answer 1

P0350 Ignition coil Primary / Secondary circuit malfunction.

This code represt not just one igntion coil but the igntion system  Here is a igntion system with a P0350, what happened in here with the igntion coil is that the cylinder valve cover was seeping oil into the sparkplug well. this did not creat a misfire code but a P0350.  Another cause is the  sparkplug that are not properly torque  can cause P0350, or failed igntion coil.  Hyudai has a TSB about this code condition what they require to satisfy P0350 condition is to replace the ignition coil connector.
