what's up everyone? i recently purchased the turbonetics kit and got it installed on my 04 g35c. after about 500 miles on it, my service engine soon light came on. i went to infiniti to get it checked and it was P1273, the a/f sensor. they reset it at infiniti and it went away momentarily and it's back on again. is it serious, and what does everyone suggest? thanks

 

non-foulers. do a search and you will find all the info you need.

 

Nope...the Turbonetics kit comes with non-foulers built into the downpipe. There is actually a TSB from Nissan about this. The ECU needs to be flashed by Nissan to apply the fix for this (its a ECU coding issue) then you need to send the ECU back to Turbonetics to get reflashed with the right tune...
