I turboed my civic, it has a dohc zc and everything is working good besides the fact that when I boost for more than a few seconds the engine light comes on for the map censor code, I know hondata or oberdata and things like that would fix it but I've pretty much ran out of money for a little while, I just need it to work before I lay it up for winter... I heard something about check valves but where exactly on the vacume lines do they go and how many do I use?
