first make sure all your connections and soldering is good
then you might want to reset your computer.

i did solder them together, so the connection is good. and i did reset the ecu......i think that all theres is left for me to do is get the connector and replace my o2 sensor..........by the way did u do this and your light went off? or you just goin by what youve heard/read? it is throwing a o2 sensor code, so i know thats the prob, but i cant seem to fix it.....thanks

hey your O2 sensor should reach fine. I have a 99 Ex and mine reached ok. Plus don't bother emailing them. They won't respond. You have to call them and you will get someone within a couple of minutes.
