even if you made bungs for the rear 02s many people still get an SES light. If you can cope with some downtime, TexasSpeed (one of our sponsors) can delete the codes if you send them your ECM for less than the cost of new 02 sims. Then again used 02 sims go for around 50-60 dlls on the FOR SALE section pretty often.

Yep. Disconnect them and ziptie the wires out of the way, or plug in O2 sims. Are you on easternfbody.com? I'll be up for the shootout at MIR on April 2nd and can probably help ya out if you're going. Have HPTuners and can delete the codes in a few minutes.
