Watch the video in reverse. There's a secret message in there that says something like: "A coupler BLEW OFF on the way back from the gas station. So we returned it back to stock."

I believe the problem is the lack of drivability of the vehicle when it is experiencing a MASSIVE VACUUM LEAK. I don't know, maybe its something to do with unmetered air entering the engine?

Got anymore astounding advice?

i mean why would you even run your car like this its just stupid! you dont even have it hooked up to the throttle body morons
