The rear o2 sensor just needs to have a working heater circuit, I have an o2 simulator that will "handle" the emissions part. Let me know shipped price to 75217.

I can almost guarantee as soon as you replace the heated (secondary) O2 that you will start popping pre-cat codes.

 

The o2 was already bad but the heater still worked until recently and i started getting the p0141 code. I had the o2 simulator for about 7 years now with no code. I might try using a resistor, i forgot which one to use, so ill have to google it i guess. BTW Scott, did you ever get that VB modded?

Nevermind, just saw your car was rip.

 

Yeah, 6MT 5.5 gen now. No need for a shift kit now.

 

I haven't had any luck with resistors - two 10ohm is series worked for about 900 miles then the codes came back. FWIW, o2 sims only take care of a few codes and not ALL secondary codes accommodating popular belief on this forum. Codes such as P0140/1 and P0160/1 need o2 replacements (or a successful series of resistors).
