Hi there. I have a corsa trip 3 cylinder and im getting an engine management light on all the time. I have had this checked and its something to do with the wasted spark. Apparently because its a 3 cylinder it has to vent the 4th spark somewhere and its this which is sticking. Now i believe that it can be removed and cleaned out but i have no idea where it is. Can anyone tell me where it lives so i can clean it out, the amber light is doing my head in now. My email is [email][/email]. if you send me an email can you put corsa in the subject box so i dont trash it. Thanks Craig
