E6X high idle

[Blairis]

I have a e6x running the sr20de in my datsun. Had it tuned 4 months ago and everything has been fine until last week. The idle has jumped up to 1400rpm when cold and then settled down to 1200Rpm when warm. If I unplug the icav the idle reverts back to normal. I have looked for vacuum leaks and can't find any, I also changed the PCV valve as I changed the rocker cover a few weeks ago this didn't help either. Any ideas??

Watch the output to see what percentage it is running. Also check your TPS is at 0% and the Min Duty is not too high. These things do not change over time, so something has happened to cause the issue.
