    It did come back, the day after this post, I removed the 02 sensor and sodered the resistor inline on the blue wire. No more CEL's, well worth the $.89....

    yea i have a 04 wrx and i just ordered the HKS turbo-back hiper exhaust and the up-pipe. all i have to do is order the Eliminator from pony express and splice into the blue wire of the 02 censor right? my stuff is on the way but i think imma go ahead and order the CEL eliminator to get rid of the problem before it occurs. but i just splice it into the blue wire right?

    and the 1mega ohm resistor idea won't work on the 04 wrx right?let me know. thanks

    Read the rest of this page.
    The 1Megaohm resistor does work on '04's. I have had it in for 2000 trouble free miles. Whether this is from the UTEC or not remains to be seen.

    As soon as I read this thread update, I got a CEL last night. Within 5 mins. of reading it. Wierd.
    Looks like i'm driving my truck for a while. Too damn cold to crawling around under the car after work. Plus I know it runs alright. More than likely a cat innefficiency code. We'll see...
