i have a 1.6 impreza and i have a missfire its ok when you accelarate slowley but when u put the foot down it coughs and splutters i done a fault code check and its showing the injectors are away does this sound right and would injector cleaner solve it or would i need to replace them cheers

 

Not sure what you mean when you say the injectors are 'away' but if an injector fault is showing, it's unlikely to be solved by injector cleaner, although for a fiver it's probably worth seeing if it makes any difference. Best would be to take them out and service them or just replace.
