odd problem bank 2 lean i have a 99 z, car has a lid fast toys ram air and exhuast.
the car is throwing a bank 2 sensor 1 lean.
car surges like it has a vacc leak......which is what i will be testing first.
but what else could cause a lean code?
the only things i can come up with is iac, egr, or an inj. but the iac and egr would affect both banks, and the inj would not cause the car to die when idling....any other thoughts?

ok well that wasnt it. replaced 02 still has a miss, still running like ****, and still throwing a lean code, which is not constant...i really need this fixed, its my dd. car is costing me a fortune to drive right now.
what could cause just one bank to run lean? and what could be so hard on it that it would die, but not throw a miss fire code?

Mine was doing the same thing but it was for bank 1. I did what NVR SPDS said to do and replaced the 02 sensors, it did nothing. Then I cracked open the valve covers and saw I had a floating Valve Stem Seal replaced it and bam, fixed the problem. I don't know if this has really anything to do with that code but it worked for me and it is just a idea.

I have the same problem with bank 1 my car does not die and it is random. I swapped the left and right 02s and the problem whent away for 300 miles or so and now is back.. I can not find any vacume leaks and have not taken off the valve covers to look at the valve terrain.. The car runs good.
