Car running lean as ****.

Few background bits of info

pfi kit t4/t04e ball bearing - leaky

swapped 555cc injectors in again after replacing busted o ring

My wideband o2 is reading 22-23 a/f ratio... at idle... wtf?...

as far as i know, fuel is getting through the fuel rail - fuel press is at 34 psi.

Are there any other causes that could lead me to be running this freakin lean

fuel pump, fuel filter? Did you run lean with the stock injectors?

fuel pump is fine - excellent pressure - fuel filter has less than 1k on it... it didnt run lean with stock injectors

I'm not sure why they wouldnt - they were working ok before besides them being leaky b/c of the o rings..

using e-manage?

maybe try running the car without the fuel pressure regulator, maybe its not reading right? Pinched fuel line?

Yeah i'm using e-manage - it's not the fpr or a pinched line - i've got 2 fuel press gauges reading from different ports and they read about the same

Alot of widebands dont pickup well at idle. I wouldnt be too concerned about that. Take it out for a spin and see what the a/f gets on partial throttle.

My techedge wideband reads 25:1 at idle because it cant really read the idle a/f too well and just resorts to the highest reading and sits there till it is given some gas.

I guees I'm just tripping out because before when the car was leaky, it'd read really rich - like 9 - 10:1....

hopefully that's all it is.... guys i really appreciate the handful of replies in less than 5 minutes
