ok the new car is still failing emissions and my temp tags are now expired by a month. frank leta honda has been little help.

i'm throwing codes p0170, p0171, and p1457. i've replaced the gas cap, injectors, and the o2 censor is fine.

car is a '97 civic dx coupe, w/ a y7 bottom and y8 head. i'm smelling fuel every once and awhile while driving. bank 1 is lean.

fuggin help. i'm tired of leaving 15mins early so i can duck into lots if i see cops so i don't get pulled over.

tia,
kelly

Just to save some people some google time:

P0170 Fuel Trim Malfunction
P0171 System too Lean (Bank 1)
P1457: EVAP Control System Leakage

Do you know what ECU is in the car?

I would try the vac lines(specifically the ones that go to the charcoal cannister(does it still have a charcoal cannister)

from what i have been able to research..

check the fuel filter and the fuel pressure regulator.. for the first two codes

for the 3rd...check vaccum connections to the evap canister and also check the evap purge solenoid...

did all that. when i had it diagnosed, they gave me a print off of everything. hence why i said honda hasn't been any help.

If you want, I can swing by and take a peak under your hood some time this weekend.
