I recently Installed a 70MM BBK Throttle body and my check engine light came on. There is almost like a whistling noise as I accelerate. So people say it could be a vacuum leak, some say it's because of the new throttle body. I've even put the stock body back on and still heard the noise so I'm pretty sure it's a vacuum leak but cannot find it. Also, my exhaust is leaking now. Not in idle but when I accelerate then let it sit you can see it leaking from the chamber. Any Ideas? Thanks in advance.

Use carb cleaner to carefully spray around the intake area, when you hit the vacuum leak the engine idle will change. What chamber are you talking about that you can see the exhaust leaking from?
