Service Engine Soon - P0174

Vaibe · 02-28-2015, 10:15 PM

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
