Auxillary Air Pipe(s)

[doctorDHD@xxxx]

I just noticed that the metal pipe that connects to the rear of the Idle 
Speed Regulator is very loose on the end I can't see. Where does this end go? 
How do I check it?

The pipe that connects to the cold start valve is also a little loose under 
the manifold. What is the easiest way to tighten this?

Pehaps this is why 6530 doesn't idle well?

Thanks again,

Dave & 6530
