My 1994 Accord Wagon, 172k miles, failed emissions for NOX. I am told that
my combustions chambers is running "hot" but the Catalytic converter may
still be ok. One suggestion is to add some alchol before trying the test
again and also to make sure the engine is a cool as possible. Someone
else<g> has told me to get some magic additive that is sold in auto parts
stores to fix my problem...another genius suggests a run of Gum out.

I am willing to spring for a new catalytic converter if it fails a retest
and if that will certainly fix my problem. Can anyone explain what my
problem is, in layman's terms, and the validity of some of the helpful
suggestions from my buddies?

Thanks,

Mark
