cel question

[longjeeper]

ok so everytime i use my nitrous, my car throws the p0172 code, which states that bank one sensor reads too rich.....now i replaced the plugs and the car runs fine, and the code only goes off after i spray....is there any way to fix this, or do i just have to deal with it? the car is an 05 gt cvvt 5spd and i am running 70 shot gets on the street and 80 shot jets at the track, and i only use the nitrous when its aroun 900 psi, and the bottle is only on when i am racing thanks for any help

I dont know if you read FordfasteRRs thread about the nitrous jets but you may need a smaller one for the fuel since our cars runs so rich from the factory

yeah i read that and i run the smaller fuel jets to compensate like stated in fords write up....

hmm very weird then

the only way to know would be to hook up a wideband on it (with gauge)
