Anyone know an o2 sensor that will get rid of the CEL from a high flow cat? I would like to get one that has actually worked for someone before I get it...I've heard mixed things about aftermarket o2's.
Also what will a wideband do as far as a CEL goes?

Kinda noob questions but I'm a little buzzed and don't really care...

 

Buy a O2 simulator. Advance auto parts.

 

Ok, what the heck is that...

Sorry, noob question again

 

Basically, what it does is extends the O2 sensor further away from the center of the pipe so that it doesn't lay directly in the exhaust gas stream.

 

just get the rear o2 deleted with HPT.

 

Ok I'm going to be honest. With these cars and tuning, I really don't know much of anything. I'm seriously a noob when it comes to anything past basic bolt ons....someone please walk me through this!

I would like to get HP Tuners, but I know nothing about it, and I have no idea about this o2 delete...
