I have a problem, Right where the tube from the air cleaners connect into one, You put you hand on the hose and when you rev the car, It's makes a loud bang noise and something feels like it bangs on my hand, I have a 85 Sport Coupe, 2.8, V6.

 

Could be a backfire, could you give us some background info on the car? Recent things done to it, has it just started doing this, etc?

 

We put another engine in it, I didn't do anything to it, As soon as we were done with it, We started it up and it did that
