*****PROBLEM HAS BEEN SOLVED, THANKS***** (Coupler came off from the Throttle Body)

Just received/installed my Needswings Dual CAI for my N/A.

Was a little bit difficult to install, and took me ~5 hours to do it. (First time changing an intake on a car, ever)

Had a HELL of a time getting the coupler onto the throttle body, and it was pretty difficult to get the Y split into place. Actually, it seems like there isn't enough room to do this right, as my whole intake sits slightly to the left.

Anyway, I got in the car and turned it on. Revved it, and it sounds like it's running open-throttle. Sharp sucking sound when I depress the pedal. I notice that it lags a lot too. I'll push the gas pedal down, and nothing happens for about 1 second, then it rev's.

More driving around and I hear whistling while accelerating (I assume that is normal), but here's where things got weird. My XF started to bog and it felt like I lost a LOT of power. Once it cleared 2000 RPM's it was fine, back to normal at least.

Idle was a little rough for a while, (I disconnected the battery for 10min, and let the car idle for another 5min, and it went away).

I checked all of the connections (coupler to throttle body, elbow to coupler, etc.) and all are connected, and clamped tight.

Just got a check engine light and my car shut off on the freeway going ~85mph. (Luckily I didn't panic and die, just pushed in the clutch, turned off the key, and started again). Made it home no problems.

I guess my question is, what the hell went wrong!?

I'm letting my car cool off so I can investigate right now, but does anyone have any ideas?

I have no idea why just swapping the intake would make my XF lag so much.

Any info/tips would be great.

Thanks,
Eric
