Hello boy. 1 °- The Boya Metódo consists of a KE deposit connects to the Iny rail. And to which you add the cleaner and already closed the deposit, you put air with a compressor (commonly).
2 °- Did you have the vehicle? or does it start to fail and go out? A good reason is the KE mentions Kikimec, the other is that it is possible to any component can fail and turn off the car ..... from a sensor, an actuator or to the key, the alarm ... etc. etc. That is why it is important to observe the details of the fault. When failure? hot? cold? at a certain speed? In idle a stop? ..... I hope you understand me. Salu222222222
