Hey CL! So my check engine light came on and I ran obd to check it and it came back with p0141. I went 300 over my oil change and another thing is a while back ago I cut a small hole in my air box just to make the car sound a meaner upon acceleration. Could that be the problem? Also the code was Oxygen Sensor Heater Circuit Bank 1 Sensor 2. Someone please point me in the right direction. Thanks!
