after almost a year of looking at that stupid CEL, and realizing that my highflow cat/catback plan isnt going to pan out as soon as id like, i installed my 02 sensor simulator (which i COMPLETELY forgot i had purchased during an ebay addiction phase). it was alot easier than id expected, and im quite happy with the results. MANY props go out to 'funky techician' over at Mazda3forums.com for a pretty decent writeup with pics included. throw in a little of your own ingenuity and youre set...
