Throttle sensor

Engine misfire is related to the fault of throttle position sensor. If the throttle position sensor is good, the engine misfire will be good.

It may be so. The 4S repair shop suspected an accidental failure for the first time, so I cleared the fault code for you. But the staff will tell you that the sensor has been changed. In fact, this fault was not handled, so the fault light came on again after running for a day. That's what people in 4S stores usually do.
