Po174 bank 2 lean

Elmo370z · 12-13-2014, 03:28 PM

My car threw this code today. It happen while I was waiting in line to enter a car show which I never got to enter!. I was in line for about two hours stop and go, towards the end the motor sounded like it wanted to stall. It was running around 220-230 the whole time waiting in line. I just got the code cleared, driving around the tomorrow to see if it comes back on. Anyone has any experience with this code? How much of a concern is this.

All I have done are stillen gen 3 intakes. This is the first time this has happen, I also was experiencing high idle 1,000-1,100 rpms. Tighten the gas cap that didn't help.

Vacuum leak on that side? Check the pcv hoses off the intake.
