Removed Cyclone Intake Manifold Now Car Won't Run

[b00stedeclipse]

Well it was a nice evening the other day so I decided to get rid of the cyclone intake manifold that came with my motor and swapped it out with the USDM one (ECI Multi). I carefully paid attention to everything that I disconnected. Installed the USDM and connected everything back up and the car wants to start, rpm's go to about 2k and then back to 0 and stalling out. Doesn't run for any more than 2 seconds or so. Anyone know if there's something I am missing going from the so-called jdm manifold to the US one? I have all my vacuum lines that were on the old one run to the new one. I never had the cyclone manifold functioning properly so thats why I pitched it.

Any help would be greatly appreciated!!

Hey boost leak test for the win.

Seconded, but also go through all of your electrical connections as well.

All electrical connections are fine - boost leak test tomorrow morning. Thanks!

I had something sort of similar happen to me when I forgot to tighten down a mounting nut/stud (Just one out of the 8 or so) on the drivers side of the intake. I lost 10 mm Hg ish during idle and would barely run. But yeah a boost leak test will show this

Also properly adjust your throttle cable.

Check the Vac lines on the TB also may have left one of them off..

Sounds like a JDM 1g throttle body. Does it only have the P port?

It would appear so. I have to be missing something major for it to not remain running.
All bolts are to spec on the manifold. Here's a shot of the TB.

Is your PCV connected to the manifold? the picture kind of makes it look like it isn't.

Yes it is, its just tough to see it going underneath the main harness and throttle cable.
