What's the effect of dirty throttle?

When the throttle body is dirty, it only affects the "starting" performance, and there are many aspects as follows: 1, which affects the vehicle starting: it is difficult to start. 2. Affect the idle speed of vehicles: the idle speed is unstable, too high or too low, etc. 3. Affect the fuel consumption of vehicles, which may increase. 4. Affect other parameter values: such as throttle opening and stepping motor steps collected by ECU will be affected, and errors will occur, such as ignition advance, fuel injection timing and fuel injection quantity. , will lead to engine conditions, increased fuel consumption, engine jitter and other adverse conditions. 5, the acceleration is weak, and it is impossible to speed up: for example, the throttle is stuck. 6, emissions are not up to standard. 7, car, hair and other anomalies. 8. Other anomalies: The possibility of other faults is not ruled out, which should be determined according to the environmental emission standards (European standards) and vehicle models. When the throttle is found to be too dirty or other abnormal conditions, it is recommended to send it to after-sales service for maintenance and solve the problem in time.
