Hey guys, I just finished my STI swap and had my key programmed today. I go to start it up and makes a weird sound, almost like it's gulping or something. After that, it idles perfectly, warms up perfectly, etc. Once I go to tip in the throttle, it makes a sound like it's gargling or something. It comes from both sides of the engine and only happens when I tap the throttle. Other than that and the same sound happening when the engine starts, it runs perfectly. No smoke, no smells, nothing. Not the middle, but both sides.. almost like the heads?

Any ideas?

Ignore the white smoke, it was just burning off whatever fluids seeped into the seals. It doesn't smoke anymore when it idles.

Wow... that sounds weird. Almost sounds like plastic smacking something, or something in the intake..??.. What did you disassemble on the engine before swapping or did you just drop the entire motor in, already assembled?

There may be some kind of air tubing disconnected, almost sounds like some type of solenoid cycling. check the bov connections and the smog stuff, if it has any
