2010 CX-9 FWD Touring with 185K
OBD-II Codes:
P0174 system too lean bank 2
P0204 injector circuit/open cylinder 4
P0304 cylinder 4 misfire detected
I’m thinking this is most likely a bad fuel injector for cylinder 4. With all the effort to get to the fuel rail and injectors, I’m wondering if it makes sense to replace all six injectors while I’m in there, even though I’m only getting the codes for cylinder 4, especially given the age and mileage.
