Serious or not? Urgent!
I was driving home today from Youth Group...and I noticed my car has a fluttering sound to it. Its espcially noticable when you punch it, and let it run up about 1k rpms. It sound's like there is a flap in the manifold or something. There is also a metallic sounding flapping coming from underneath the hood.
It sound's like a WRX, but its never sounded like this before. And when I take it up to 4krpms or so(in 5th gear), it has the bubbly sound...like its running rich. I took it to Inline today, for John to adjust my v-afc cause I upped the boost from 5-8, and this afternoon is when I noticed it.
When it idles, it has a consistant rumble to it...like a V8.
What should I do?
Am I running rich?
Did a vaccum line come loose or something?
Is it the wastegate?
Should I be concerend? I'm gonna take it to Inline toomorrow and see what they say!
Thanks!

Yea, I'll check the lines tomorrow!
The only guage(s) I have is a boost guage and a v-afc.
Its a flapping sound...kinda like a whirring...like a WRX. Not a pinging or rattling sound...and its very consistant.

I've got the same thing going. I know mine is from a leak at the turbo. Make sure you have the turbo bolted tightly to the manifold and downpipe. That's all mine it, but since the engine is coming out soon, I don't care....

*Update*
I went to start it this morning, and it barely started. I rev'ed it up to 3k or so a couple times, and when I let off, it would drop down to 500rpms or so, then go up to 800(where it usually idles).
So had a loud "knocking" sound to it? It sound's like a metal sheet is flapping under the motor or something.
Could I have thrown a rod or something? Valve? Bad gas?
I really need to know, cause I'm hoping to sell my motor/turbo setup soon, and it its screwed...then I'm screwed.
Thanks!
