EGR Valve Tube

exuast leak......... help
Alright, I just installed my JBA headers two days ago. I paid a shop to do the work as I have no time for the install. Yesterday I noticed a very rough Idle while cold but once it warmed up it would idle fine. I then noticed today a put put put sound coming from under the hood. I figure an exuast leak. I take a peak and see that the EGR Tube had been melted away leaving a large hole. I can see the exuast coming from the metle tube where the EGR tube runs. Is this what was causeing my rough Idle and is that tube suppose to be rubber or metal?

I would also check to make sure that the plug wires are properly routed and seated on the plugs. They had to have been removed during the header installation.
The EGR tube is steel and the short hoses that tee off of it to the DPFE sensor are silicone rubber.

so that would cause the rough Idle. It only happens in the moring when the engine is very cool throught the rest of the day i can leave it for 6 hrs and come back and it works great except now for the PUT PUT PUT sound comeing from the drivers side. The tube was resting on the header pipe and melted away. Would puting flex hosing on fix the melting issue? I guess it goin back to the shop tommorrow so I can yell at them. I am in the army, I love to yell at people.

On your 2001 4.0L, there should be a steel EGR tube that has a fitting screwed to the driver side header collector. It should mount and function exactly as it did when it was mounted to the stock DS cast iron manifold. The short rubber tubes should be a long way from the header.
