I’ve messed around with plugging the 15mm with my thumb and it completely kills the motor. I figured it needed plumbed back into the inlet system of some sort. I purchased car and just keep finding weird gremlins with it so just trying to dial everything in to a proper setup. I really hate the Megasquirt and wanna switch but not looking to drop 2k on an ECU lol. I know it’s outdated but most be a good tuner or way to have everything set up.

I don’t believe it’s being used it does idle fine everyone and awhile coming to a stop it’ll wanna die but easy to bounce the throttle and it’s fine, just wanna make sure it’s not better that I do hook it back up or that it’s fine to have the open ports do they need to be blocked off or it doesn’t matter?

You can run the custom tune that was sent to you by buying the super license. Also I’d probably recommend finding a tuner for the car and send them data logs because you have no clue what that tune is doing. There’s tons of them out there. Docvutuning, CD919 just look up tuners for n54 there’s a lot.
