p0172 too rich bank 1 5vz-fe

bump

Were you ever able to figure this out? I am struggling with a p0172 along with intermittent P0130/P0133 codes after swapping out all 6 injectors for flow tested OEM Aisins.

 

Similar issue here. I feel it has to be involved with the injectors. I am leaning towards faulty new, looking to get the old set refurbished. New set has to be dumping when i am at idle. Been road testing and cant get the code to pop on highway but in a parkinglot or driveway it keeps coming up. I live near Winston Salem NC. Is there a particular place to send these injectors in my area?

 

Have all exhaust flanges been inspected. I also think these on my truck have seen better days. Looking into cleaning it up with new cats and bank 1 sensor too.

 

are your injectors "new" off Amazon or ebay?
