Service Engine Soon - P0174
 

Hey I had this light come on the other day and I went to autozone today to have them read the code for me and it came up with P0174 Bank 2 System too lean.

I haven't really notice anything with the car although it does seem to be idling weird, it sometimes jumps up and down make 200 rpms when idling. Before the light came in, I was idling in the car for maybe 30 seconds, noticed the RPMs dipped really low and felt like the car was about to **** off, RPMs went back up then the light came back on.

Give us some background info on the car, any recently installed mods?

Ah yeah sorry! It's a 09 370z, 36k miles on it and it has a stollen CBE and a stillen CAI. Nothing else, they were installed about a year and a half ago

Weird. It just turned off by itself today. Guess all is good? Haha

Clean your MAF's.

Yeah id say clean mafs and filters and check for exhaust leaks

I just had them erase the code and it never has popped back on for me. I only have stillen g3's. it happen to me while i was sitting in traffic for 2 hours
