EA2 1 1 Slow throttle return.

1 and EA2 1 1 The slow return of the throttle is due to the small throttle opening and the small air intake. Some very fine dust and exhaust gas from the engine valve chamber will be deposited on the air inlet of the throttle and idle speed control valve, resulting in the problem of slow response of the throttle.

2. First of all, we can unscrew the bolt and nut fixed by the air filter and take out the filter, so that we can see clearly the situation that the steel wire rope affects the opening and closing of the throttle. 2. Then, if it is found that the bending amount of the wire rope is extremely small, it means that the wire rope is very tight. Even if the driver releases the accelerator pedal, the throttle cannot be completely closed, resulting in continuous fuel supply. 3. Another simple method is to step on the accelerator with one foot to see if the accelerator can stand up, that is, to judge the fault completely.
