To FI INC.

I'd like to say I like how you are showing passion and care towards your customers. Repped

We appreciate the positive words! In my book this is the only way it should be!

Thanks, Tony

I am taking the Z to my GT-R Master Tech (He is the tech who installed my headers and CBE) this evening and hopefully we can come to the bottom of this. I cleared the codes earlier this week with my PC as a test to see if they would come up again and they did infact after about 200 miles. I will update you with what we conclude today.

Thank you very much for the reponse Tony.

I have been debating which headers to go with. After reading this thread...Fast Intentions all the way. Customer service has sold me.

Tony,

Do you offer HFCs installation at your facility? I would feel much better having somebody at your facility installed them

Please keep me posted. Once you have a conclusion it will be better for you to call me directly. You will be able to get a hold of me right away...

Thanks, Tony

Pleased to hear it. If you have any questions at all or when you are ready to place an order, please do not hesitate to call me directly...

Thank you, Tony

Call me!

Good morning Tony,

After leaving my sweet Alorah(Z) at the dealership for the past 3 days I finally was able to pick her up yesterday evening. The day I dropped it off I had both codes thrown and as I said in my previous statement I erased these codes only to have them come back again. The Technician working on my car only used torque wrenchs on the installation he claimed as this was the first question I asked him. I told him what I had read on this forum and how there was only one other incident of this happening out of (I said over 100 units sold) since I do not know the exact number. The Service Rep begin to blame the codes on the headers and then continued to tell me I didn't do enough research before I bought this unit. I quickly proceeded to tell him I did months of research and kept my self very informed via the 370z community and even yourself Tony. I also noted that after 12k miles this is my first issue directly or indirectly related to the headers that I have encountered. I told the tech to re-check the wiring and individually test the O2 sensors and everything was working properly after those tests. The Tech told me he could not pinpoint the issue since he could not get the codes to appear again once he cleared them. After picking up the car yesterday I have already put 100+ miles on the vehicle and I have not seen the codes as of yet. However their entire story and reasoning/answers behind everything greatly displeased me. I felt like I was getting the run around. Long story short the dealer/tech could not resolve the issue and cleared the codes. Any suggestions Tony? (I have noticed the car is running smoothly once again after the codes were cleared as it was running a bit rough previously)

Bump for answers!

T.

Glad we were able to talk on the phone and troubleshoot the potential cause! My ideas would of just been too much to write here!

Keep me posted as to what you find out...

Thanks, Tony

I appreciate the time you took to reach out to me over the phone and give me some much needed direction! I will keep you informed on the outcome of the tests. And that's for sure, you'd have written a novel! Haha!

Thanks, Troy

Really interested to see if this was resolved.

Peppers,

First of all congrats on the headers and welcome to the FI family.:tup:

I too had issues but not because of the headers but only because of installer ignornace.

I kept throwing a misfire code and a cataletic code which in return meant the 02 sensors.

Many cleared codes later and lots of trouble shooting. Come to find out. The damn shop put the 02 sensors in the wrong place. The primary was put inside of the J bend and the post cat was put inside of the header where the primary should of went.:shakes head:

BTW check your MAFs also on the intakes. Mine were dirty.

Hope this helps and FYI Tony has the best customer service hands down:happydance:

To me, this was a pretty cut and dry mis-wiring of the O2 sensors.

I goofed up mine the first time (to my dismay, since they aren't cheap).

I would bet that this was resolved by correcting the wiring and replacing the sensors.
