Hey everyone ...

 

I have a 2015 1500 with a V8/5.3. It's got 93,000 miles on it and after rebuilding the transmission at 90K (ugh), I'm now throwing a code for the catalytic converter. What kind of issues (upstream) lead to a catalytic converter failure? I just want to cover all my bases here. Additionally, anyone have any luck 'cleaning' a catalytic converter (if it's clogged) either by fuel additives (skeptical) or physically removing the converter and cleaning it? Thanks guys.

"Look for burt or shorted o2 sensor wiring.  Cats don't fail like that. And if it was clogged you would now it due to sluggish accel and bogging."

 

Unfortunately, I am getting a sluggish/bogged acceleration. Clogged?
