My idle reads from 1200-1500rpm which seems a little high to me. It seems like it just started doing this. It is not surging or anything. Just a high idle. How do I lower it?
If it was fine and now its not that tells you something has screwed up. I wouldn't adjust anything. Pull the codes, check for vacuum leaks and check/clean the iac. When mine did that this past summer, it was a vacuum cap that had came apart.

for help with your idle problems. The first post contains all the updates to the fixes. I continue to update it as more people post fixes or ask questions.
I think before I just wasnt paying attention to how high it was idleing but I guess it was high before too. It was probably adjusted like that because the previous owner probably thought it would run better or at least sound better with the cracked head and mild cam. I did try to disconnect the IAC and nothing happened.
