I replaced my Upper/lower IC pipes and catalytic converter last night. I have an O2 fix on the pipe after the now 3" straight pipe. The straight pipe I replaced the catalytic converter with has a bung for O2 fix but I plugged because there is already an O2 fix after the new straight pipe. This evening my service engine light came on.

Should I: 1. Swap the sensor a place in the new pipe and close the old hole.
2. Buy one of those 12 volt O2 fixes from Buschur.

HELP.....

 

man that was hard to read. anyways, i would just do a mechanical o2 fix and quit messing with the electrical stuff. it is cheaper anyways. good luck.

 

so is this the fix you did?
