well if ure refering the pathake mis-firing, the reason is the naked coils located so openly on the Tapet cover, as soon as water (wen u get the car serviced) touches it they get short. then kharab hojati hain. Coils change krne k baad bhe yeh masla hai then u may need to get ur Tappets adjusted.
Santro is the only car which has a predefined warning not to use water in the engine bay,
but we are Pakistanis still living in the Carborator world hum to dabba k panni lagwate hain engine mein,
Uske bad deisel spray krai bagair to chain nai atta takke aur mitti lag jai.
