Well, I got a surprise in the mail today... got my notice for emissions testing. I've been running with my CEL on for more than a year with the P0138 after having my dual channel sim installed (my guess is improperly, obviously)... but I kinda need to know if anyone has installed one of the dual channel sims onto both the secondary sensors successfully. This would obviously be the cheapest fix, as it would just need to be redone. Thanks guys!

 

Eh I'm giving up trying to get it to work. Thankfully I have my stock y-pipe with an in-tact and functioning cat. Had o2 bungs welded on behind the cat, and hopefully I can get the wires extended.

For those that extended theirs, what gauge wire did you use? Will any electric kind of wire work or is a specific kind needed? Thanks!
