O2 Sensor problem after FI LTH install

scott982 · 12-05-2011, 08:03 PM

After another phone conversion with Tony I believe we have solved the problem. The mechanic used an impact to remove the demon bolts and the vibration destroyed 2 of my o2 sensors.

Thanks for the call this morning. I am sure once the wires are taken apart and then soldered back together you should be fine. Since it is an issue only on one side, I am quite certain it is just an installation issue.

Call me back if you need anymore advice.

Lastly, I look forward to getting your exhaust out to you so you can enjoy it with our headers...

Thanks,

Thank you so much for all the help today. I can't wait for the catback to get here.

I will overnight those new wires out tomorrow. You live and you learn man. I had to learn the hard way a while back for the same thing. I ended up buying that customer a new sensor. As we all know, they are not cheap for this car!

So I assume the solution to this is to pull the O2 sensors before you start disassembly?

You do not need to pull the manifold sensors before you remove the stock cats. You just cannot use impact tools on the cat bolts. I never do for this reason.

When I install the headers I pull the sensors after I remove the cats. I find the front sensors easier to get to with the cats out of the way.

Thanks, Tony

That is not a good thing. Scott982 explained to me on the telephone that power tools were used during the removal of the stock cats. We determined the power tools destroyed the front O2 sensors from the vibration they created.

He purchased 2 new front O2 sensors and has not had any issues since!

Please do not hesitate to call me if you have any questions...

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.

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
