cleaning cat converter

[91accorddoor4]

i have to go for my emmissions (sp) test tommorrow and i'm blowing black carbon smoke at higher rpms,i was wondering if theres a way to clean out my stock cat converter without ruining it.i am taking it off tommorrow morning to see if its clogged,i dont feel like buying a new or used one so does anyone know how to tell if its clogged and a way to clean them out.thanks.

Mine's doing the same thing as yours, black smoke at high rpms...I also have blue smoke at high rpm's but thats from me burning oil. Wish I could help but I'm looking for a possible easy fix or anything that would help it too.

black isnt bad, white is..

just run it on the freeway for 30 minutes....

u cleaned ur egr ports so u should be fine, either than the HC that may show up if u fail which is ur distribitor cap and rotor.

black yellow white red whetever colour the smoke is,,,, there is something wrong with the engine. it has black smoke when u floor it right???? i had the same problem with both of my hondas. u are burning rich at high rpms.

don't worry about passing the emition. i has ur problem and my car burned oil and i still passed the emitions for the past 3 years.

Yeah my car burns oil, smokes blue and blak smoke at high rpm's, and it passed emissions with flying colors. my friend was driving behind me tonight and said he was getting pissed off cuz my car was making all these weird smells.
