line blows off ,runs poorly

I have a 01 range 3.0L with 57k miles, today a line blew off the tube from the egr exhaust line reinstalled it started truck everything seemed ok drove off and it blew off again. It looks like it comes off the exhaust side of the egr, there is pressure coming out of the steel line. There are two lines next to each other the other one stays on, they go up into a box on the front of intake. truck is running like it is losing timing. though it could be pluged exhaust??

Thanks for any heads up info

Could be a blown diaphragm in the EGR valve, or maybe a plugged DPFE/transducer? (the box that feeds control vacuum to the EGR dome). Is your CEL on? The OBDII code will should help troubleshoot this.

Think i may have found problem. believe it to be pluged conveter.

Hmmm... I'd be suspicious of that. Your 2001 will light up the CEL & give you a code from the downstream O2 sensor if you have a cat issue.
