Cheating the sniffer?

[abatzis2@hotmail.com (Michael Abatzis)]

hey ray--you're car shouldn't be putting up close to those numbers with a 
new cat. if you've double checked your mixture, i'd suspect the cat is 
bad--remember how you said you thought it was rattling? one of the cat's 
main purposes is to reduce NOx. if you want to swing by this weekend, we can 
take a look at it together if you want.
