2jr intake issues

[zsjohnson0]

What’s up! It’s been a few years since my last post.

Just installed the 2jr cowl intake (sounds amazing imo) and I’m getting some rev hang on deceleration/in neutral. Usually at 800rpm and 2-3 times it’s gone up to 1800-2000rpm. I used the stock Pcv intake adapter and connected it to the tubing that 2jr provided. I’m realizing that’s probably the issue? I’ve seen that some have used the fix kit from Whoosh with success. For some reason I am not finding the Cobb kit that 2j says to use. Anyone with similar issues? https://whooshmotorsports.com/colle...4c-check-engine-light-fix?variant=45058456654

I'm assuming it's a 2016+ FiST. I have a '14 so I'm not super knowledgeable on the fix kit situation. If you don't have the fix kit, I'd go ahead and get it. Couldn't hurt. Do you have the P144C code? Additionally, I would do a thorough double check of everything. Anything you touched during the install. Clamps, connections, line routing, etc. It's easy to miss something small, or even something big when you're excited and/or frustrated working on your car.

Best I've got, hopefully someone with some '16+ experience can chime in and give you something more definitive.

EDIT: If you can, I'd probably just convert to the '14-15 EVAP harness.

Yeah it’s a ‘19. Called 2J and they said they plugged off the evap port, so I did the same. I don’t have the P144C code but it’s throwing a P2282 and a P0507 still, but sounds like I should convert to the ‘14-15 EVAP system since it’s a single line. Still weary of the stock pcv intake adapter too lol
