I have a 2000 International (Amtran) 444e this morning while sitting at a light foot on the brake the thing got real loud and rough sounding, Like a hole in the muffler. Put it into neutral and it sounds fine. Or if I rev up the engine it sounds and acts fine...

I do not see any holes or blowouts in the exhaust but have not crawled all the way under just yet..

Tell me have I lost my mind??

Sounds like the waste gate on the turbo opening and closing.

I was formally Baptistbusman. However, I lost my password, and had not updated my email address.

Update:

I'm assuming this is the fuel filter housing (?) Sits on the top of the engine more towards right side if you where looking out the front drivers window.
There is a wiring harness has three wires two in the front and one off to the side. The top wire was corrioded and burnt not even attached. I put a new connector on it and plugged it in (International dealer did not know what I was even talking about). I'm assuming this is causing it to run rough while in gear foot on the brake. It also has a lack of power for a split second while taking off. Anyway I reattached the wire and it still is running rough. Any ideas or can guide me.
This is a 2000 International T444E Engine (3800) series Am Tran bus.
