Alright so I know the Code 43 tends to be a difficult one to diagnose so I figured I would offer my tragic backstory when this started happening.
Couple days ago we had our sheer number of rainstorms in the area, at the time I was still running my Injen cold-air intake (that goes down into the wheel well near the front bumper) without any fender liners. Long story short I was driving on the freeway when the rain hit and ended up sucking a lot of water into my intake (even with a hydro bag) so much so that the car really started to misfire badly, to the point where I was on 2 cylinders for a couple of seconds throwing white smoke out my exhaust and getting water in my oil. I ended up draining all (if not most) the water out with an oil-flush the same day. And put back on the stock intake for the winter months. I made sure to reset the ECU (battery method) to make sure the car would start fresh. Now my vehicle throws a code 43 typically when driving on the freeway for about a min. Could the O2 sensor have gotten damaged in the event with the misfire? Could I have damaged my fuel injectors with the water? I have not driven it much since the incident started to get a good idea on gas mileage, I have no issues with bogging or being slow (other than removing the performance intake), but it definitely smells rich from the exhaust. The O2 sensor was replaced about a year ago when I was throwing a Code 41 (ECU ended up being the issue) I would hope this story would help narrow down for some who has been somewhat knowledgeable in this area regarding the fuel system.
Many thanks!
