Car running Rich and Lean
Posted: Thu Jun 19, 2025 6:00 pm
I'm experiencing a problem with my 2014 Civic Si; it seems to be struggling to drive. It's running rich, but also lean at the same time, causing the vehicle to jerk because it wants to stall. All I have done to the car is just an exhaust and running hondata reflash. I have changed the O2 sensor before, and sometimes the code P0172 pops up.
Please help.
