Sorry for making so many posts, I promise I'm searching my ass off before posting. So I did a y8 intake manifold swap onto my y7 the other day and my idle is about 2k rpms constantly. It eventually drops to 1100 and to keep the story short it seems like this is a common problem in this swap. I'm pretty sure, after reading, that it's because the manifold that I got was from a 99 - 00? (Only speculation from what I've read) how can I figure out what year this came out of and what do I do about it? I read jb weld the air assist ports closed?
