The catalyst material can be lodged in there tight, not allowing it to rattle, but it could still be plugged up. Can you redline the tachometer? You could try removing the upstream o2 sensor and take a quick run up the road to see if your acceleration is back, that'll tell you if its plugged.

Same here.. 2 weeks after cat replacement had to replace the upstream O2 sensor and just 2 months ago repaired the plenum with a hughes kit.. It wasn't leaking real bad but did start to have a little oil usage and more then just a slight wetness to the inside of the intake and had 2 weeks off of work for X-mas so ordered everything ahead of time and was able to take my time on the repair..

I bet that code you're getting is a cylinder mis-fire, maybe #8.
Is there any other way to try an get the codes? I have tried the key trick several times and it does not work for me. If I had the code maybe I could get a better idea.

Where the hell did you get peanut brittle from ? lmao
1. Crawl under your truck
2. Next to the tranny, tap on the catalytic converter (cat)
3. If it rattles (like peanut brittle loose) then you have a clogged cat
Mine did the same thing. It would idle ok, but under load it would not even go 30mph, then it dropped to 5 mph in a matter of 10 min. It left me stranded.
4. If it is the cat, you can either remove/replace the cat or gut the cat (open it up, remove the insides and close it again)
good luck
