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?
