Hello, my name is***** sounds like your purge solenoid has failed which could cause all of these codes. The purge solenoid allows fuel vapor back into the engine. If purge solenoid is sticking open it will allow too much fuel vapor back into engine making it run rich which are the P0172 and P0175 codes. Replace purge solenoid, here are replacement instructions. Let me know if there is anything else I can do to help. Thanks.-https://www.dropbox.com/s/rvt0a9va194yold/subpurge.pdf?dl=0-
Still getting all of the same codes?
