Found the problem. Ended up being the catch can not being sealed.

[SOLVED] High STFT at idle but when I bill the throttle it goes back to normal.

That’s why the smoke and pressure test wasn’t working, the check valve from the intake to the catch can was preventing the smoke and pressure from being seen.

One would think a smoke test at idle would have drawn it in? How'd you end up finding it?

[mention]Stephen Mcneill [/mention] [mention]Awafrican [/mention] I’m interested in this as well. I’m having similar issues with idle. I have smoke tested and pressure tested the entire system, but I am having intermittent issues at idle. AFR will blip up and down as well as STFT. I’m going to attach a log for review. But, I have smoke tested every and it holds pressure under the boost test.
Before tearing down my OCC, I’d like to know how he found that to be the issue.

You will probably be better off posting your own thread regarding this issue if you want help with troubleshooting. Include all the relevant information per the "Troubleshooting Sheet" post at the top of that forum.
