Ok long story short engine started pinging at low RPM's took it to the dealer and they said there was a code for idle too high. Also the AF ratio was at 130 and should be 95?? So they did the idle relearn under warrenty. The car is still pinging and they have no clue whats wrong..
they accually told me to remove my Nismo stuff and go back to stock to see if it goes away. OK it wont and I no longer have the stock stuff anyway..They also told me just to drive it with it pinging it should be ok. Um not it wont. I have called Nissan of America and they are looking into it but they are pointing to my mods for the issue.. Any help here guys. I know the CAI and the cat back is not casuing the problem but there is no check engine light on either?? Thank you

 

I would move it, but I saw this:
