Those of you who have the Alphawerks Header what kind of intake do you have and do you have a CEL? do you have an o2 sim or anti-fouler and still a CEL?

Reason being is I just intalled the header with the anti-fouler and I still have a CEL but i have an Injen Intake and i'm wondering if it could be the increase in airflow on both sides that could be causing the CEL so i'm taking this survey to see who has the injen/alphawerks combo and if having another intake makes a difference. thanks

the theory is, is that the second obd2 sensor get to hot with out the pre-cat so that is why the cel comes on. I have read the the non-fouler works for some people and others it does. make sure that all the bolts for torque correctly and that there are no leaks.

I have ZPI's O2 Sim, but I don't have it on yet. I'm waiting until my UR Crank Pulley comes in to do it. It's supposed to arrive on Monday so I should have an answer back on here by Tuesday.

hey guff, lemme know if that zpi o2 sim throws a CEL. u got it for roughly $100 rite?

robFMtC

so you guys don't think it could result from the intake?

which o2 sim do you think will work better? Alphawerks or ZPI?

Yeah it was $95 plus shipping, off of thescionstore.com. I would think the ZPI O2 Sim would work the best, it's supposed to correct A/F ratios instead of just get rid of the CEL, so that's why I went with it, otherwise I would've gladly paid $20 for the anti-fouler, haha.
