2018+ Roush Supercharger Throttle Body

[Goterr0r]

Hey guys,

If you take your intake tube off going to the throttle body, is your throttle body completely closed when the car if off? Or does it slant with a little slack that you can push on for it to be fully closed. I've been hunting an intermittent issue with idle hunting and this looked out of place.

Thats normal. It’s probably the cam phaser causing your issue. If the tune is on point.

The tune appears to be on point and this revision has been on for a few months now. It went into limp mode today after a cold start and gave a pending PO61b. Looks to be MAF, intake tract, or TB from what i can tell. Since it has a Roush supercharger it doesn't have a MAF and the intake box, tube, and filter all look good. I can't find the digital to analog throttle body converter on the early 2018 models so i look to have a digital TB. Is this just a GT350 TB or something else?
