Some knucklehead made me slow down going through deeper than expected water and the car stalled. I was able to restart, and it started sputtering terribly the rest of the way home with check engine light flashing the whole time. Gave it 2 days to dry out. No change.

Seems to be ok above 2500 rpm but getting there is an issue. I don't know a lot about engines. Please be gentle.

Taking to get code checked for the flashing cel in a few hours. Should I be scared?

Check plugs, check if the filter is soaked. Can crank the engine with no plugs to see if there's water in the cylinders. Check the wires for cracks

The cel has been on since i bought it. Previous owner said it was because he used non oem injectors. I assume that is the cause of the misfire codes.

It's running better today after some early struggles.

Should I try some catalytic converter cleaner and go?

I wouldnt use cat cleaner. Get some correct injectors from a junkyard, see if that helps. Maybe replace the primary o2 sensor if the codes for it come back. Use only denso
