Unhappy 2010 2.0T genesis coupe stalling

Hi guys, I have a 2010 Genesis coupe and almost every day it does not start at some point. Some times it just does not start and some times it starts but then within 10/20sec the revs drop and it stalls.

ODB reports p605 and p2105 error together but clears the CIM light by itself after a day or so. There is a tech bulletin out which says to replace the ECM module but I am not sure that this is the right fix.

Mode 6 data shows that a misfire did occur on cylinder 4 and another time it was captured on cylinder 1. I am suspicious that the evap monitor 0.090" is at -1432 and the max value is -1400 which makes me wonder if I have an evap problem.

Any suggestions to narrow the fault down?

The problem can possibly be either a dirty fuel filter or a faulty O2 sensor. Have those inspected.

You need an ECM update
Needs to be done by the dealer
Believe there is a TSB (technical service bulletin) on this
When a P2105 occurs with a P0605

Was was for a Sonata?? Check with your dealer
