Apropo de MTIA la spark :
Recently has proven to be that at Matiz 1.0 the motortoerental can hang continue because of a broken affirmative propeller in the house of the MTIA (Motorized Throttle idle Actuator). This problem has only arisen at cars in Korea but the serial concerned MTIA's has been also applied in export implementation. Concerning then Matizzen 1.0 produced between 16-12-02 and 14-03-03rd solution: To exclude some risk GM Daewoo have to decided change the implementation of these propellers. Cars of which the suspicion exists that these are carried out with MTIA from the suspected serial, must be checked on the production number (destiny number) of the MTIA. If the destiny number falls within the interval 2M12 up to 2M26 the MTIA must be replaced.
