Need some help with my mustang. Its a 97 v6 3.8
Took it for a smog and it failed.
I got codes:
p0443 EVAP purge control valve CKT malfunction
p1131 no description
p0171 System too lean (Bank 1)
p0174 System too lean (Bank 2)

How can I fix it? Can I do it myself? What is OBD system check? Because that failed!

Any help? Please!
