I have test pipes and a borla TD and after I installed them my check engine light came on and there was a rattle. The rattle ended up being one of the O2 sensors which is broken or something is loose inside and that also may be why the check engin light came on. I need to know if an O2 sim completely replaces the O2 sensor or attaches to it etc. I would also like to know how much they cost and where to get them. Thanks.

 

Check Casper Electronics. they make some for almost every car

 

radio shack, make your own, cheap

 

sorry for my ignorance but what does an o2 sim do?

 

COntact skidazzle. he makes these 02simulators and they work great. I think he sells them for $30 shipped.

 

got any info on how to make your own O2 sims? I'd like to give it a shot.

 

thanks for the info
