Lude Acts

Nice. Let us know if that's it. Like I said, I kinda doubt it, but at this point, you've already tried nearly everything else, so it can't really hurt. Just the fact that your CEL went away on it's own made me think it could be a gas cap issue. Also I think somebody told Speck on PreludePower that they had a cracked vacuum cap on the throttle body that was barely visible (the crack) but let in just enough air to have a vacuum leak and cause a misfire.

Also Speck, have you done the EGR port cleaning yet? It is alot easier to do than the write-up makes it sound. Once you get into it, it's a piece of cake.
