help... my O2 sensor sucks!

[Killride]

So I finally installed my whole catback and header from evofusion, I wrapped the header with heat tape, also installed a high-flow catalitic converter... and extended the o2 sensor to the back, and today the CEL light came on... I did everything they told me, install a cat and extend the 02 sensor behind.... now I dont know what to do.....:confused:
any ideas???

yeah same here, i have the evo fusion header and cat back exhaust. i was running with no cats and i got tired of my cel so i bought a magnaflow cat and extended the o2 sensor behind it and put the stock resanator and it still throws a cel

well....what now...LOL
when I put the oem setup it goes away!.... LOL....:tongue:

[aduran]

use a normal cat for engines up to 2.5L thats all or a OEM ;)

using a high flow doesn´t work

^true or get an o2 fouler.

[Killride]

o2 fouler....? or the sparkplug fowler?
because I tried that and didnt work....:Blasting_

I dont know what else to do....but if I cant get rid of the CEL, I will put the oem header back and sell the EF headers..... I even installed a catalitic converter and cost me $150!, not to mention the high temp tape ($50) and the itching for days because it was fiberglass... im dissapointed after all that money and work:(

would installing a wideband o2 sensor help??? :confused:
