i jsut put in a b18c. didnt wire vtec right so i thought the cel might be because of that. so we got it right and the light went off. ok so thats cool but once i punch it and the secondaries open up and i get the light. now i havent checked to see what code is being throwin. i think its because im runnin open headers. could this be why im getting a light? and how to you check to see what code it is?
