ok fellas heres the deal. i need to go get my car smogged in a couple of days so ill need to clear these codes ASAP.any help is greatly appreciated.
i have four codes:
p1131
p0171
p0133
now these can all be cured by replaceing the 02 sensor for the upstream bank number 1 (position 1).
but i also have:
p0174
which isnt listed as a code that you get when the above 02 sensor is bad. does anyone know what i need to do. thanks for any help.
