So the owner before me straightpiped it and the CEL went on. Before I bought it I did get the code read and I remember it was something about the Rear o2 sensor. So would buying a CAT make the CEL go away? Are there other solutions? I don't feel like buying something to trick the senor.

 

there are several fixes for this, it depends if you want to hug a tree or not.

 

Downloading TEPHRA will fix it

 

Well what are those fixes? If I have to hug a damn tree to make the light go away then I'm all for it.

 

You missed his joke. Tree huggers run cats, scoot over to the ecuflash forum and grab some popcorn and order a cable

 

Or I can sell you a cat delete that wont throw a CEL. I still have it around from my old setup, my new DP has cat eliminator built in and I am running standalone ECU. Basically it has o2 sensor bung offset from the cat, which pulls the o2 sensor out of the exhaust stream and doesn't throw a code. $60 shipped paypal included. let me know

 

I'll think about it, I might get the Ultimate Racing tp tho

 

That cools, just thought I would help out. PM me if you decide you want it. I have been holding on to it just in case one of my friends wants it or if my setup changes and I need to put it back in for some reason. lol

 

Sorry man, the easiest way to do this is to trick the sensor. You can find o2 sensor spacers on eBay for 13 bucks shipped. It will back the sensor out of the cat about a centimeter or so, so that the exhaust gases aren't as concentrated as they would be at the sensor. Technically your o2 sensor is still measuring exhaust gases, just not as much.

 

Yeah I was thinking that too after reading some stuff earlier, problem is its hit and miss, but it definently saves money. I wish the works cat didnt cost so much $$

 

2 spark plug anti foulers = no more P0420 code

Disabling the code routine in the ECU= no more P0420 code

 

Spark plug anti foulers work for me.....I just had to enlarge the center hole so the o2 would fit. Real cheap n real easy!!
