Default Engine shuddder

My '01 had a rough idle and has now progressed to a shudder at idle to about 1500 rpm and also picked up an acrid burning smell and a smoking catilytic converter. Did some research online and looks like its the ignition coils. I'm a newbie at this so any thoughts?

Replaced the coil pack and the shudder is gone. Truck is running like new again.

Ok so the truck ran well for a while and now it popped a code for 401 for an egr blockage. Replaced the egr valve and that didnt work. Still have a horrible shudder and the first catylitic converter was smoldering and smoking. I can't find a replacement egr tube and i'm wondering if i could get away with removing the tube and replacing the exhaust along with new manifolds or headers (if i have the money). any suggestions on what I can do? please help on this i've got no clue.
