I DONT KNOW WHY I MUST BE THE ONLY PERSON WITH THIS PROBLEM I INSTALLED THE FI TEST PIPES AND EVERYWHERE I SEE NOONE GOT THE CEL ON AND MINE WONT GO AWAY EVERY TIME I RESET IT IT JUST COMES BACK...ID REALLY APPRICIATE SOMEONE HELPING ME DO AWAY WITH THIS PROBLEM PLEASE WHAT IS GOING ON

 

Why are you yelling? Chill dude

Could be a damaged sensor

 

call tony. maybe u need to ship them back

 

LOL yeah try going back to where you got them from and have them look at it.

Caps lock off please.

 

Call Tony, You may need nonfoulers.

Youre not the only one who had this problem.. N_Jay888 (Neil) just went back to Fast Intentions this weekend because his CEL came on because of his F.I. HFC. Tony took care of it from my understanding. Aint that right Neil?

 

sheesh, please practice proper netiquette.

couple questions,

what's the weather like over there.
how long have you had the vehicle
who installed your test pipes. were you being careful with the o2 sensors?

you do realize that even with defouled exhaust pipe, that second o2 sensor is designed to be pretty sensitive.? if you're running cat-less you should expect to have your CEL on... defouling can assist the situation but it's not a 100% solution preventing a CEL light to temporarily come on.

 

Did you try using steel wool yet?

 

OP you have a Black sedan?

 

never trieed a steel wool alot of people i know dont have this problem i was extremely careful with the sensor theres not much to be careful with it didnt hit anything and i screwed it on nice and tight being careful... and to people who dont like how i type please hop off thats not the point of this thread can someone give me tony's contact info

 

His username is: F I Inc, Fast Intentions

 

Proper grammar and punctuation makes your pleas easier to read and more likely to receive assistance. See? Was that hard?

 

I had same problem with catalytic converter. The installer instead of using gasket. Made seal with silicone. And when silicone melted. And started to leek. I got CEL also. See if any exhaust air is leaking.

 

Getting the P2A03 CEL with ERZ HFCs on my 2010 G37xS sedan. Going to keep digging into this. I'm 99% sure there's no leak, and I do have the 90 degree angled non-foulers/spacers. I hope it's not a case of the newer ECUs being sensitive to the point where an HFC/TP mod isn't worth the trouble/risk.

 

no he has a ip coupe.

dont mind the caps, thats how he really talks in real life. lmao

 

What code are you getting, btw?
