Now that my ZXT is running again, I don't know what I did but it idles at below 750 rpms regardless of being in park or in drive.
The revs go up when its cold (~1100 rpms), just like it should, but they no longer stay at 1k when warm!
But I don't know how I fixed it....
Sorry Blue, I hope you can figure it out. (I didn't miss with the AFM btw, timing at 17 deg, and I did clean a lot of parts)
