Is it normal for a car to run rough after replacing an O2 sensor?
After replacing an oxygen (O2) sensor, it is possible for a car to experience rough running or other performance issues. This is because the new sensor may need time to adjust to the vehicle's exhaust system and send accurate data to the engine control module (ECM). The ECM uses this data to adjust the fuel-air mixture, which can affect the car's performance.
In most cases, the rough running will subside within a few minutes or hours of driving. However, if the problem persists or worsens, it is important to have the car inspected by a mechanic. There may be another underlying issue that needs to be addressed.
