X2 tooo short message......... yea CC If it is the CC, these things have precious metals in them. Take it to a scrap dealer.

possibly incorrect timing advance

and/or clogged exhaust system.

you will have to remove the exhaust to check.

Catalytic converters become clogged because of something else going wrong. Either too much fuel being dumped, contaminants in the fuel, etc....

If the cat is glowing red, it probably needs replacement because it has gotten so hot that the catalyst may have melted into a lump or the ceramic portion may have cracked.

As stated, you need to drop the pipe(s) in front of the cat(s) to see how the engine performs. If needed, replace the cat(s), but be prepared to check the truck out right away in case the components you replaced were not the cause.
You wouldn't want to mess up a new cat!

We have great pricing on converters for your truck
